Prilocaine Impurity 11 CAS CATO-C4X-193411 chemical structure

Description

CATO manufactures Prilocaine Impurity 11 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

Prilocaine Impurity 11 (CAS CATO-C4X-193411) is a certified pharmaceutical impurity reference standard with the molecular formula C16H18N2O and a molecular weight of 254.33 g/mol.

The molecular framework of Prilocaine Impurity 11 (C16H18N2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
