Chemical Structure

Chloroprocaine Impurity 10 CAS 500338-95-4 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 Chloroprocaine Impurity 10.

CATO supplies Chloroprocaine Impurity 10 (CAS 500338-95-4), a pharmacopoeial impurity reference standard (molecular formula C13H19ClN2O2, MW 270.76 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C13H19ClN2O2, Chloroprocaine Impurity 10 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 270.76 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), Chloroprocaine Impurity 10 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.
