Chemical Structure

Eltrombopag Impurity 89 CAS 1097777-60-0 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 Eltrombopag Impurity 89.

CATO supplies Eltrombopag Impurity 89 (CAS 1097777-60-0), a pharmacopoeial impurity reference standard (molecular formula C13H9NO5, MW 259.21 g/mol) used for the identification and quantification of trace impurities in APIs.

Eltrombopag Impurity 89 (C13H9NO5) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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 Eltrombopag Impurity 89 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.
