Chemical Structure

Atracurium impurity 99 CAS 155913-37-4 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 Atracurium impurity 99.

CATO supplies Atracurium impurity 99 (CAS 155913-37-4), a pharmacopoeial impurity reference standard (molecular formula C22H30NO4C6H5O3S, MW 529.65 g/mol) used for the identification and quantification of trace impurities in APIs.

Atracurium impurity 99 (C22H30NO4C6H5O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

CATO manufactures Atracurium impurity 99 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.
