Chemical Structure

(E)-Benzhexol Impurity 12 HCl CAS 67562-42-9 (free base) chemical structure

Description

As a certified reference material (CRM), (E)-Benzhexol Impurity 12 HCl 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.

CATO supplies (E)-Benzhexol Impurity 12 HCl (CAS 67562-42-9 (free base)), a pharmacopoeial impurity reference standard (molecular formula C20H29NHCl, MW 319.92 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, (E)-Benzhexol Impurity 12 HCl is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 319.92 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
