Chemical Structure

Resmetirom Impurity 45 CAS CATO-C4X-291245 chemical structure

Description

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 supplies Resmetirom Impurity 45 (CAS CATO-C4X-291245), a pharmacopoeial impurity reference standard (molecular formula C7H12Cl2N2, MW 195.09 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C7H12Cl2N2, Resmetirom Impurity 45 contains a nitrile group, chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 195.09 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.

CATO manufactures Resmetirom Impurity 45 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.
