O-Ethyl-O-(4-Nitrophenyl)Phenylthiophosphonate [Content ＞15%] Detailed Product Information

What is O-Ethyl-O-(4-Nitrophenyl)Phenylthiophosphonate?

O-Ethyl-O-(4-Nitrophenyl)Phenylthiophosphonate stands out as an organophosphorus compound with more than 15% active content. The structure centers around a phosphorus atom bonded to both phenyl and ethoxy groups, along with a strongly electron-withdrawing 4-nitrophenyl ring and a sulfur connection. This configuration brings together stability and reactivity in one molecule, often required in chemical synthesis, specialized manufacturing, and research applications. In any laboratory, seeing a compound with such specific functional groups means it often plays a key role in modifying other molecules or acting as an intermediate in more complex reactions.

Molecular Structure and Properties

With a molecular formula of C14H14NO5PS and a molecular weight near 339.31 g/mol, this substance shows a clear presence of both aromatic and phosphorylated functionalities. This is not a simple hydrocarbon or mild ester; you’re dealing with a dense, highly engineered compound. At room temperature, it typically appears as pale yellow or colorless flakes, crystalline powder, or occasionally as small pearls depending on the grade and storage conditions. The density tends to hover around 1.38-1.41 g/cm³, making it more substantial than most standard organic liquids and powders. Each batch tends to be dry, solid, and only marginally hygroscopic, which means storage should steer clear from open air and exposure to excessive moisture.

Physical Characteristics

You’ll recognize O-Ethyl-O-(4-Nitrophenyl)Phenylthiophosphonate by its appearance as solid flakes or crystalline powder, easily handled with standard laboratory scoops but not something to leave lying open because of potential volatility in certain conditions. Some preparations appear in fine powdery form, offering a higher surface area for reactions, while others show up as small pearls for easier weighing and reduced dust. Solubility varies by solvent: it tends to dissolve in organic solvents like acetone, ethyl acetate, or dichloromethane, but barely mixes with water. The melting point generally sits in the range of 60°C to 80°C, which should be respected when storing near heat sources or in warmer climates.

Chemical Behavior and Hazards

From experience, working with this material means not overlooking its hazards. The sulfur-phosphorus bond alone doesn’t tell the whole story; the nitro group introduces toxic properties, particularly when the substance is inhaled or absorbed through the skin. Despite being stable at room temperature, it decomposes at higher temperatures, releasing toxic fumes such as nitrogen oxides, phosphorus oxides, and sulfur compounds. Direct contact produces skin and eye irritation. Handling always involves gloves, splash goggles, and chemical-resistant clothing. Proper fume hoods are an absolute rule for any task that generates dust or aerosols. Storage calls for tightly sealed glass or plastic containers, labeled under toxic and hazardous chemicals, far from food and incompatible chemicals like strong bases and oxidizers. One careless moment can turn a routine transfer into an incident involving exposure or contamination.

Product Specifications and Regulatory Compliance

O-Ethyl-O-(4-Nitrophenyl)Phenylthiophosphonate goes by several identifiers, but in international trade and customs, it carries an HS Code of 2930909099. This codification places it among organic phosphorous compounds, subject to country-specific regulations due to its toxicological profile and uses. The chemical’s purity, typically above 98% for research or industrial use, gets confirmed by chromatographic techniques along with melting point and spectral analysis. If bought as a raw material, the supplier provides reach-compliant documentation for hazardous chemicals, including detailed hazard communication sheets. Import and handling require strict record-keeping, licensing in some countries, and always an eye on environmental management, as spills cannot go into drains or ordinary trash.

Applications and Raw Material Relevance

This compound rarely ends up as a consumer product on its own. Manufacturers seek its ability to donate or substitute functional groups in more complex reactions. In specialized synthesis labs, the thiophosphonate group reacts with bases or nucleophiles, producing derivatives useful in materials chemistry, pesticides research, and as analytical reagents. Not all raw materials deliver such reactivity or selectivity. While not a mainstream industrial chemical, it demonstrates how targeted molecular engineering creates building blocks that enable downstream development in fields ranging from environmental chemistry to pharmaceuticals. Use as a precursor means the purity and handling determine the reliability of the final product—one contaminated batch can lead to a failed synthesis or worse, toxic byproducts.

Safe Use and Environmental Stewardship

Safety with O-Ethyl-O-(4-Nitrophenyl)Phenylthiophosphonate is not negotiable. Training for staff covers more than just donning gloves—storage, transport, emergency handling, and waste disposal must be ingrained in workplace culture. Neutralizing spills, using absorbent materials, sealing contaminated equipment, and ensuring wastes enter approved hazardous chemical disposal streams prevent site contamination and health risks. Offsite transport adheres to the IMDG and IATA guidelines for toxic substances, which means no improvisation in packaging or labeling. Conscientious users log all quantities for auditing and reporting, reducing the odds of illegal use or improper disposal. The conversation about chemicals like this often circles back to accountability: responsible sourcing, careful handling, prompt cleanup, and rigorous adherence to the rules keep labs and communities safe and limit harm to the environment.
