Tucatinib Impurity 17 CAS CATO-C4X-260517

Description

Compared with other compounds in its class, the molecular weight of 345.40 g/mol gives Tucatinib Impurity 17 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Tucatinib Impurity 17 (CAS CATO-C4X-260517) is a certified pharmaceutical impurity reference standard with the molecular formula C20H19N5O and a molecular weight of 345.40 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Tucatinib Impurity 17 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 345.40 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).

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 Tucatinib Impurity 17 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.
