Chemical Structure
Description
The occurrence of Avatrombopag Impurity 42 is closely related to a nitrile group, sulfur-containing functionality, chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Avatrombopag Impurity 42 (CAS CATO-C4X-223442) is a certified pharmaceutical impurity reference standard with the molecular formula C7H3BrCl2N2S2 and a molecular weight of 330.05 g/mol.
The molecular framework of Avatrombopag Impurity 42 (C7H3BrCl2N2S2) is characterized by a nitrile group, sulfur-containing functionality, chlorine/bromine substitution, an aromatic ring system. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
CATO manufactures Avatrombopag Impurity 42 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.
