Chemical Structure

Clarithromycin EP Impurity A CAS 124412-58-4 chemical structure

Description

The occurrence of Clarithromycin EP Impurity A is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

As a process- or degradation-related impurity, Clarithromycin EP Impurity A (CAS 124412-58-4, C38H69NO14) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

The molecular framework of Clarithromycin EP Impurity A (C38H69NO14) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

CATO manufactures Clarithromycin 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.
