Phenyl phosphate

Phenyl phosphate (CAS 701-64-4 ), also known as monophenyl phosphate, is the monoester of phosphoric acid with phenol. It functions as a reactive intermediate and catalyst in pharmaceutical synthesis and polymer processing. In pharmaceutical manufacturing, it serves as a key intermediate for synthesizing phosphorylated active compounds and prodrug systems where selective ester linkage is critical to the final API structure. Polymer formulators use it as a flame retardancy additive and reactive modifier in thermoplastic systems. Its phosphate group contributes to char formation during combustion, enhancing material safety and performance. In biotechnology and life sciences, it acts as a substrate or reference standard in enzyme assay development. It is particularly useful for phosphatase activity studies and biochemical research applications. It also functions as a catalyst precursor in specialty chemical synthesis where controlled acid-phosphate reactivity is needed. This versatility makes it a valuable component in complex chemical manufacturing. Phenyl phosphate is typically supplied as a crystalline solid or powder. It is available in technical and high-purity grades suited to pharmaceutical intermediate and research applications across various industries. Packaging ranges from small quantities for laboratory and R&D use to bulk quantities for industrial procurement.
