Chemical Structure

Eltrombopag impurity 143 CAS CATO-C4X-1198143 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 143.

CATO supplies Eltrombopag impurity 143 (CAS CATO-C4X-1198143), a pharmacopoeial impurity reference standard (molecular formula C14H14N4O, MW 254.29 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C14H14N4O, Eltrombopag impurity 143 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 254.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 143 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.
