Phenyl phosphate

Phenyl phosphate (CAS 701-64-4), also known as monophenyl phosphate, is the monoester of phosphoric acid with phenol.

Where is Phenyl phosphate used?

• Pharmaceutical synthesis: reactive intermediate for phosphorylated active compounds and prodrug systems with selective ester linkage
• Polymer processing: flame retardancy additive and reactive modifier in thermoplastic systems
• Biotechnology: substrate or reference standard in enzyme assay development, including phosphatase activity studies
• Specialty chemical synthesis: catalyst precursor where controlled acid-phosphate reactivity is needed
• Its phosphate group contributes to char formation during combustion.

Commercial specifications

• Technical and high-purity grades
• Packaging from small laboratory and R&D quantities to bulk industrial quantities
