Bilastine Impurity N5 CAS 29205-99-0

Description

Compared with other compounds in its class, the molecular weight of 178.22 g/mol gives Bilastine Impurity N5 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Bilastine Impurity N5 (CAS 29205-99-0) is a certified pharmaceutical impurity reference standard with the molecular formula C11H14O2 and a molecular weight of 178.22 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Bilastine Impurity N5 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 178.22 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.

As a certified reference material (CRM), Bilastine Impurity N5 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.
