Chemical Structure

Avibactam impurity 92 CAS CATO-C4X-134892 chemical structure

Description

CATO manufactures Avibactam impurity 92 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.

Avibactam impurity 92 (CAS CATO-C4X-134892) is a certified pharmaceutical impurity reference standard with the molecular formula C7H11N3O6S and a molecular weight of 265.24 g/mol.

Owing to a carbohydrate-derived structure, an amide group, a sulfone group, Avibactam impurity 92 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 265.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
