Chemical Structure

Doxorubicin EP Impurity B CAS 148218-14-8 chemical structure

Description

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

CATO supplies Doxorubicin EP Impurity B (CAS 148218-14-8), a pharmacopoeial impurity reference standard (molecular formula C29H34BrNO11HBr, MW 733.40 g/mol) used for the identification and quantification of trace impurities in APIs.

Doxorubicin EP Impurity B (C29H34BrNO11HBr) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 Doxorubicin EP Impurity B 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.
