Ibrutinib Impurity 56 HCl CAS 61644-00-6 chemical structure

Description

CATO manufactures Ibrutinib Impurity 56 HCl 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.

As a process- or degradation-related impurity, Ibrutinib Impurity 56 HCl (CAS 61644-00-6, C5H9NOHCl) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Ibrutinib Impurity 56 HCl (C5H9NOHCl) contains an amide group, a hydroxyl group, an ether linkage, chlorine 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.
