Triphenyl phosphate serves as a flame retardant and plasticizer in PVC, resins, and nail polishes. Classified under HTS 2919.90.50 as a 'other' phosphoric ester, it matches the heading for non-substituted phosphate triesters. Its aryl phosphate structure distinguishes it from alkyl phosphates or derivatives.
