Chemical Structure

zanubrutinib Impurity 4 CAS CATO-C4X-21014 chemical structure

Description

CATO manufactures zanubrutinib Impurity 4 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.

zanubrutinib Impurity 4 (CAS CATO-C4X-21014) is a certified pharmaceutical impurity reference standard with the molecular formula C23H26N4O and a molecular weight of 374.48 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, zanubrutinib Impurity 4 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 374.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
