Bilastine impurity 120 CAS 2409938-73-2

Description

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.

Bilastine impurity 120 (CAS 2409938-73-2) is a certified pharmaceutical impurity reference standard with the molecular formula C12H15ClO and a molecular weight of 210.70 g/mol.

Owing to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, Bilastine impurity 120 is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 210.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO manufactures Bilastine impurity 120 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.
