Ivermectin EP Impurity A CAS 65195-55-3 chemical structure

Description

CATO manufactures Ivermectin EP Impurity A 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.

CATO supplies Ivermectin EP Impurity A (CAS 65195-55-3), a pharmacopoeial impurity reference standard (molecular formula C48H72O14, MW 873.08 g/mol) used for the identification and quantification of trace impurities in APIs.

Ivermectin EP Impurity A (C48H72O14) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
