Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 226.70 g/mol gives Bilastine impurity 90 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Bilastine impurity 90 (CAS CATO-C4X-225390) is a certified pharmaceutical impurity reference standard with the molecular formula C12H15ClO2 and a molecular weight of 226.70 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, Bilastine impurity 90 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 226.70 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.
As a certified reference material (CRM), Bilastine impurity 90 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
