Chemical Structure

Benidipine Impurity 41 DiHCl CAS 144243-28-7(free base) chemical structure

Description

As a certified reference material (CRM), Benidipine Impurity 41 DiHCl 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.

Benidipine Impurity 41 DiHCl (CAS 144243-28-7(free base)) is a certified pharmaceutical impurity reference standard with the molecular formula C9H18N2HCl and a molecular weight of 190.72 g/mol.

Owing to chlorine substitution, Benidipine Impurity 41 DiHCl is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 190.72 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
