Chemical Structure

Vildagliptin Impurity 93 CAS 2444-28-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Vildagliptin Impurity 93.

CATO supplies Vildagliptin Impurity 93 (CAS 2444-28-2), a pharmacopoeial impurity reference standard (molecular formula C14H22O2, MW 222.32 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Vildagliptin Impurity 93 (C14H22O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.

As a certified reference material (CRM), Vildagliptin Impurity 93 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
