As industries worldwide intensify their focus on high-performance liquid chromatography (HPLC) for both research and regulated pharmaceutical production, demand has rapidly increased for highly specific reagents that ensure reproducible, interference-free results. In this dynamic context, 50 mM Tetrabutylammonium Bromide (CAS 1643-19-2) has emerged as a linchpin, widely adopted as a superior ion pair reagent in HPLC applications. This particular concentration delivers optimal peak separation, minimizes baseline drifts, and supports sensitive detection of challenging analytes—including polar acids, nucleotides, and sulfonated dyes—making it uniquely valuable across pharmaceutical, biotechnological, and chemical sectors.
What makes Tetrabutylammonium Bromide at 50 mM concentration stand out is its ability to create a hydrophobic ion pairing environment. The compound’s bulky tetrabutylammonium cation pairs efficiently with a vast range of acidic or anionic species, facilitating their partitioning into the hydrophobic stationary phase of reverse-phase HPLC columns. This enables analysts to achieve higher selectivity, better separation efficiencies, and improved signal-to-noise ratios, even when resolving complex mixtures or monitoring minute impurities. The result is not only enhanced performance and regulatory compliance but also increased confidence in generated data, especially when molecules of interest are otherwise difficult to resolve due to charge or polarity.
The reliance on 50 mM Tetrabutylammonium Bromide as an ion pair reagent is underpinned by several factors critical to pharmaceutical and specialty chemical workflows. Mechanistically, the reagent operates by dynamically forming ion pairs with negatively charged analytes. This process dramatically enhances their retention on reversed-phase HPLC columns, producing sharper and more interpretable chromatograms. Such efficacy is vital for active pharmaceutical ingredient (API) analysis, impurity profiling, and bioanalytical support, all of which demand consistent, reproducible results supported by validated methods.
Yet, the benefits hinge on stringent purity requirements. Any contamination, whether from boroxines, residual alkali or transition metals, or persistent organic byproducts, risks introducing chromatographic “ghost peaks,” shifting retention times, or even catalyzing degradation of sensitive analytes. Therefore, manufacturers must not only guarantee low residual metal content—typically less than 10 parts per million—but also demonstrate thorough absence of secondary amines and synthetic artifacts traceable via NMR or MS. These uncompromising standards help ensure that each batch of Tetrabutylammonium Bromide supports highly sensitive HPLC assays without incurring false positives or inaccurate quantifications. For analysts and procurement specialists seeking further detail, the technical specifications, batch documentation, and ordering options are fully accessible on the supplier’s product page.
To consistently deliver industrial-scale purity, the optimized synthesis route for 50 mM Tetrabutylammonium Bromide involves judiciously selected starting materials and meticulously refined process steps. Production typically commences with the controlled alkylation of ammonia using n-butyl bromide, generating the tetrabutylammonium core via selective quaternization. Transmetallation steps are carefully titrated to prevent overalkylation, while advanced crystallization protocols remove trace organics and metals. Relative to legacy batch methods, this upstream process sharply reduces formation of side products and residual impurities—paramount when the final product must meet the strictest requirements for HPLC compatibility.
Batch reproducibility is a key manufacturing advantage, achieved through real-time in-process controls, online monitoring of reaction endpoints, and closed-system isolation. Each lot undergoes rigorous ICP-OES analysis to verify metal content, ensuring typical residuals under 10 ppm for sodium, potassium, iron, and other catalytically active metals. The crystalline product is then dried under inert atmosphere to protect against hydrolytic and oxidative degradation. These quality strategies together enable robust scalability, supplying kilogram to multi-metric tonne quantities with precision-matched specifications—so customers from analytical labs to global pharma production sites can expect absolute consistency, batch after batch.
Meeting the evolving demands of HPLC users worldwide also requires supply chain agility and packaging flexibility. To address the full range of laboratory and industrial contexts, Tetrabutylammonium Bromide is available in three standardized packaging tiers: small-scale research quantities, mid-size process development units, and bulk commercial lots. For projects necessitating anywhere from 25 to 500 grams, the compound ships in certified amber glass bottles with desiccant for desktop analytical use, supporting rapid deployment in R&D and QC labs. Packages ranging from 1 to 5 kilograms are supplied in high-integrity fluoropolymer or HDPE drums, intended for pilot plants or scale-up runs where moderate batch sizes are standard. Large-scale users, ordering between 10 and 25 kilograms, receive material in nitrogen-purged fiberboard kegs with triple-layer liner bags, optimized for full GMP compliance, minimal risk of contamination, and secure handling in warehouse environments.
Each packaging format is validated for IATA and ADR compliance, ensuring safe transit under both air and land regulations, and is supported by real-time temperature and humidity monitoring throughout the journey. All storage recommendations are clearly outlined: the compound should be kept tightly sealed at room temperature away from light and moisture, with bulk formats benefitting from refrigerated logistics and storage for maximum stability, particularly in humid or high-temperature regions. This granular attention to logistics guarantees that end-users always receive materials that remain within specification, regardless of shipment size or distance traveled.
Every batch of 50 mM Tetrabutylammonium Bromide is supplied with an exhaustive suite of regulatory and technical documentation, underscoring the manufacturer’s commitment to compliance and support. Clients receive a comprehensive Certificate of Analysis (COA) with each shipment, detailing NMR, IR, and LCMS spectra, melting point, assay percentage, and residual metal analyses. Safety is documented through GHS-compliant Safety Data Sheets (SDS), with further transparency available via REACH registration dossiers and mandatory hazard labeling. Manufacturing and quality control operations adhere to ISO 9001 and cGMP (current Good Manufacturing Practice) guidelines, verified by routine audits and documented in batch-specific inspection records.
For regulated pharmaceutical applications, the company offers additional support through Certificate of Suitability to the Monographs of the European Pharmacopoeia (CEP) and Drug Master File (DMF) filings, facilitating seamless integration into global registration dossiers and new product development pipelines. Should customers require technical troubleshooting or regulatory consultancy, a dedicated team of PhD-level application scientists is available to advise on HPLC method development, impurity mapping, or validation documentation—ensuring that every purchase is backed by expertise as well as quality.
To support a diverse spectrum of end users, the manufacturer offers a transparent scaled-pricing model to suit both modest research budgets and the most demanding commercial production schedules. Buyers of 1 to 5 kilograms are quoted competitive rates within the 120 to 160 USD per kilogram range, with expedited shipping and standard documentation included. Scaling up to 5 to 25 kilograms, pricing improves to between 100 and 120 USD per kilogram, with options for customized COA, enhanced quality checks, and cold-chain packaging. For orders exceeding 25 kilograms, prices become fully negotiable based on annual contract commitments, with additional benefits such as dedicated supply slots, regulatory site audits, and bulk-handling consultancy on offer. As a gesture to new and prospective clients, the company extends free evaluation samples of 1 to 5 grams, allowing analysts to validate the reagent under their specific lab or process conditions before committing to scale.
