Chemical Structure

Eltrombopag Impurity 50 CAS 29418-36-8 chemical structure

Description

CATO supplies Eltrombopag Impurity 50 (CAS 29418-36-8), a pharmacopoeial impurity reference standard (molecular formula C16H18N2, MW 238.33 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C16H18N2, Eltrombopag Impurity 50 contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 238.33 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 50 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.
