Neratinib Impurity 8 CAS 13991-36-1

Description

Compared with other compounds in its class, the molecular weight of 164.99 g/mol gives Neratinib Impurity 8 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Neratinib Impurity 8 (CAS 13991-36-1) is a certified pharmaceutical impurity reference standard with the molecular formula C4H5BrO2 and a molecular weight of 164.99 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, Neratinib Impurity 8 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 164.99 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures Neratinib Impurity 8 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.
