Description
Phenyl phosphate (CAS 701-64-4) is a phosphate monoester of phenol, supplied as a crystalline powder. It is also referenced under trade designations including Nacure XP 333, AURORA KA-1620, and PA 75. No E-code applies to this substance.
In pharmaceutical and biotechnology applications, phenyl phosphate functions as a pH buffer and phosphate donor in enzymatic assay systems, where its controlled hydrolysis releases phosphate under defined conditions. It is also used in biochemical research as a substrate for phosphatase activity studies, enabling quantitative measurement of enzyme kinetics.
Phenyl phosphate is available in reagent and technical grades and is subject to REACH registration requirements for supply within the EU. Procurement should confirm grade specification against intended use, particularly for life science applications requiring documented purity. HS code 2931900090 applies for import and export classification.
