Olaparib Impurity 72 2HCl CAS 142-64-3 chemical structure

Description

CATO manufactures Olaparib Impurity 72 2HCl 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.

Olaparib Impurity 72 2HCl (CAS 142-64-3) is a certified pharmaceutical impurity reference standard with the molecular formula C4H10N2HCl and a molecular weight of 122.60 g/mol.

The molecular framework of Olaparib Impurity 72 2HCl (C4H10N2HCl) is characterized by chlorine substitution. 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.

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.
