1,3-Dichloro-2-propanol phosphate (3:1) stands as a specialty phosphorus compound widely recognized in chemical industries for its distinctive molecular configuration and versatile applications. This substance emerges from the reaction between 1,3-dichloro-2-propanol and phosphoric acid derivatives, producing a mixture where three parts of the chlorinated alcohol interact with one part phosphate. Such a ratio defines its chemical behavior and structural makeup. With plentiful use in intermediates for flame retardants, synthetic lubricants, and additives in polymers, it plays a notable role in manufacturing environments that demand robust flame resistance and chemical stability. Professionals count on precise specifications when handling raw materials and expect consistent performance once the product integrates into formulations.
Molecularly, this chloride-bearing organic phosphate displays a composite structure combining two key elements: the 1,3-dichloro-2-propanol framework and a phosphate group. Its molecular formula, C9H18Cl6O4P if considered as a trimeric mixture, presents multiple chlorine atoms attached to propane chains, all bound to the phosphate ester. This arrangement shapes its high density, an important factor during formulation or blending with other chemicals. Chemical reactivity largely comes from the presence of dual chlorinated carbons and the reactive phosphate ester, allowing participation in phosphorylation reactions, catalysis, and polymer modification.
1,3-Dichloro-2-propanol phosphate (3:1) usually takes on several physical forms, determined by synthesis methods and purity: it can present as colorless to pale yellow liquid, coarse flakes, solid mass, crystalline grains, fine powder, or rounded pearls. Commercial shipments most often adopt a liquid or semi-solid phase to streamline transport and dosage during production runs. Typical density falls in the 1.45–1.60 g/cm³ range at 20°C, and this heavy profile reflects the chlorine and phosphate content in its structure. Solubility leans toward compatibility with polar organic solvents, giving it wide adaptability in laboratory and industrial solution mixing. Although not volatile, it needs sealed, corrosion-resistant containers to prevent moisture pickup or hydrolysis during storage.
Manufacturers specify 1,3-dichloro-2-propanol phosphate (3:1) based on key metrics: assay for purity (often over 96%), phosphorus content, residual 1,3-dichloro-2-propanol, chlorine percentage, water content, and color (Hazen or APHA units). These details verify the product meets strict standards for downstream chemical synthesis or fire-retardant additive applications. The Harmonized System (HS) Code for this type of organic phosphorus compound typically falls under 292090 or its derivatives, which groups it alongside other chlorinated organophosphorus chemicals, facilitating import/export tracking and regulatory compliance.
Handling 1,3-dichloro-2-propanol phosphate (3:1) draws on experience in chemical labs and bulk manufacturing sites. Liquid flows easily at standard temperatures, but can thicken if chilled, leading users to warm storage areas and prevent solidification. Personal protective equipment—nitrile gloves, splash goggles, chemical-resistant clothing—shields operators from dermal exposure or accidental splashes. Next to methyl phosphate esters or bis-chlorinated solvents, this compound releases pungency reminiscent of chlorinated reagents. Inhalation, ingestion, or direct contact can cause irritation or more serious health risks. It deserves respect as a hazardous and potentially harmful chemical, governed by local occupational health regulations and international safety codes. All waste streams must travel to specialized disposal services to minimize environmental contamination and protect nearby communities.
My years spent in R&D taught me the irreplaceable role of compounds like 1,3-dichloro-2-propanol phosphate (3:1) as raw ingredients for advanced chemical solutions. Engineers rely on its unique properties to boost flame retardancy in foams, wire insulation, and textiles. Process chemists value its phosphorylating power, using it to add phosphorus atoms in steps toward pharmaceuticals or specialty surfactants. Operationally, I learned that choosing a high-density, high-purity batch will impact product consistency and mitigate risk of off-spec blends. Safety teams always demand that every drum or container arrives with comprehensive data sheets, up-to-date hazard labels, and SDS-reviewed storage guidance. This bridges the gap between cutting-edge innovation and baseline workplace protection.
Working around chlorinated organophosphates never grants room for carelessness. Every project involving 1,3-dichloro-2-propanol phosphate (3:1) starts with a site-specific hazard review, engineering controls like sealed transfer lines or ventilated workspaces, and a workforce educated on acute symptoms of overexposure. Emergency responders and supervisors keep calcium gluconate gel, eyewash stations, and updated first aid instructions close by—readiness that often makes a difference in the event of accidental splashes. From firsthand handling, oversight remains critical in labeling, storage segregation, spill response, and end-of-life management. Adoption of greener raw materials or upgraded containment might reduce risks in the long term, pushing the industry to balance performance with responsibility.
