Ibrutinib Impurity 70 CAS CATO-C4X-106470 chemical structure

Description

CATO manufactures Ibrutinib Impurity 70 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.

Ibrutinib Impurity 70 (CAS CATO-C4X-106470) is a certified pharmaceutical impurity reference standard with the molecular formula C5H3Br2N5 and a molecular weight of 292.92 g/mol.

Ibrutinib Impurity 70 (C5H3Br2N5) contains a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
