Chemical Structure

Pemafibrate Impurity 55 CAS 16942-56-6 chemical structure

Description

CATO supplies Pemafibrate Impurity 55 (CAS 16942-56-6), a pharmacopoeial impurity reference standard (molecular formula C8H14O3, MW 158.19 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Pemafibrate Impurity 55 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 158.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.

CATO manufactures Pemafibrate Impurity 55 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.
