Chemical Structure

Betahistine impurity 41 CAS 113985-59-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Betahistine impurity 41.

CATO supplies Betahistine impurity 41 (CAS 113985-59-4), a pharmacopoeial impurity reference standard (molecular formula C9H13NO, MW 151.21 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C9H13NO, Betahistine impurity 41 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 151.21 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), Betahistine impurity 41 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.
