Potassium Oxonate, also known as potassium 4,5-dihydroxypyrimidine-2-carboxylate, comes from the family of organic potassium salts. You see it most in a solid crystalline form, sometimes in powder or flakes, rarely as pearls or in liquid solution. In the chemical sector, it is recognized for its well-defined molecular structure and its key role as a component in several chemical processes. This compound grabs attention in pharmaceutical development, especially for its application alongside other drugs, like in the combination treatments for cancer. Its unique properties make it more than just a raw material; it's a tool shaping modern medicinal formulations and research.
Potassium Oxonate shows up as white to off-white crystals or as a powder, depending on how it has been processed and stored. The density hovers near 1.76 g/cm³, a solid figure that matches many mid-weight crystalline organic chemicals. The molecular formula is C5H3KN2O4, a straightforward arrangement, but one that packs complexity in its function. It dissolves fairly well in water, forming a clear solution, which matters to researchers and manufacturers alike. This solubility helps control dosage and mixing in drug formulations. Its molecular weight sticks close to 194.19 g/mol. Potassium Oxonate's chemical structure features a pyrimidine ring, a well-known component in genetics and pharmaceutical chemistry, setting it apart as both a biologically relevant and synthetically accessible compound.
Standard grades of Potassium Oxonate target high purity, often 98% and up, aiming to support strict quality controls. In commercial shipments, manufacturers refer to the HS Code 2933599090, which identifies it as an "Other Heterocyclic Compounds" for customs and trade. This classification smooths out imports and exports, making the supply chain predictable for producers and buyers in different sectors. Identification through the CAS number and HS Code keeps shipments traceable and compliant with regulations, particularly in pharmaceuticals and fine chemicals trading.
In storage and handling, Potassium Oxonate typically comes as a white crystalline powder or sometimes in larger flakes, depending on the production method. Powder form makes it easy to measure and mix in laboratory settings. Some producers offer it as pellets or solid chunks, mainly when bulk storage stability is needed. Rarely does Potassium Oxonate exist as a liquid; it's more stable and easier to handle in dry, solid forms. Crystals are prized in research and development, where purity and reproducibility matter most. If dissolved, it's usually done in distilled water in liter-scale volumes to prepare lab solutions.
Density weighs in at 1.76 g/cm³, and this solid form does not absorb much atmospheric moisture, so it stores well under typical dry conditions. For laboratory and industrial uses, workers often dissolve it in distilled or deionized water to create precise solutions, both for dosage accuracy and ease of handling. Solution clarity can confirm its quality; any cloudiness signals possible impurities that could interfere with sensitive reactions, especially in pharmaceuticals. Preparation involves careful weighing (using an analytical balance for accuracy), transfer to a clean vessel, and slow mixing to avoid clumping, especially when working with the powder form.
The production of Potassium Oxonate relies on sourcing pure 4,5-dihydroxypyrimidine-2-carboxylic acid, which serves as the main precursor. Potassium carbonate or other potassium salts react with this compound to form the final product. Access to high-grade raw materials influences not just price but the final purity and safety of Potassium Oxonate delivered to users. Regions with strong chemical supply chains, like China or India, often dominate production, while strict European and US markets focus more on quality assurance and documentation.
Safety data points out that Potassium Oxonate does not blow the hazard scale, especially compared to reactive metals or acids, but it’s not something to treat carelessly. It may cause irritation if inhaled or when it contacts skin or eyes, so most labs require gloves, goggles, and dust protection. Prolonged exposure remains rare in proper setups, but handling protocols exist to prevent harmful incidents. Material Safety Data Sheets (MSDS) recommend storing it in tightly sealed containers, away from strong oxidizers or acids, and in cool, dry spots. Disposal requires confirmation with local regulations, since improper disposal can leak nitrogen-containing compounds into groundwater, which brings regulatory scrutiny.
Pharmaceutical companies lean heavily on Potassium Oxonate as a key ingredient in combination therapies for cancer treatments, like alongside tegafur or other prodrugs. In these applications, it acts to moderate side effects, giving patients more balanced outcomes. Research labs use it as a tool compound to probe enzyme pathways owing to its structural similarity to uracil. There’s interest in synthesizing analogs of this molecule for new types of reagents, pushing the discovery of next-generation drugs. The food and fertilizer industries watch this compound only from the sidelines, as its roles stay mainly confined to research, production, and clinical settings. Standards for pharmaceutical use demand exceptional purity, while industrial uses take a broader approach, sometimes accepting lower grades for intermediary purposes.
At room temperature, Potassium Oxonate stays stable in air and during moderate heat exposure. The compound does not burn easily and rarely reacts with ambient moisture. Its pyrimidine ring structure creates a solid backbone, which helps explain why it behaves predictably in solution and in combined formulations. Reactivity comes into play mostly with strong acids or bases, where the salt will break down, impacting storage and compatibility with other chemicals. When people in the lab ask about its specific chemical attributes, conversations often turn to the balance of stability, water solubility, and the ability to integrate into complex molecular systems, such as those required in precision drug synthesis or analytic chemistry.
To reduce risks during handling, labs can automate weighing and transfer processes, limiting direct contact. Fume hoods catch any dust or fine particles before they spread. Regular safety audits uncover areas where protocols lag behind best practices. For disposal, collection of waste Potassium Oxonate in labeled, secure containers followed by centralized high-temperature incineration eliminates nearly all environmental risks. Where wastewater regulations apply, treatment with activated carbon before release stops contamination. Regular training for lab staff cements these routines and keeps safety a front-line concern. Producers who follow these practices build trust—not just in their product, but with customers’ regulators and technical staff as well.
