Blonanserin Impurity 33 CAS 4640-67-9

Description

The occurrence of Blonanserin Impurity 33 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Blonanserin Impurity 33 (CAS 4640-67-9), a pharmacopoeial impurity reference standard (molecular formula C9H6FNO, MW 163.15 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C9H6FNO, Blonanserin Impurity 33 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 163.15 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), Blonanserin Impurity 33 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.
