As a certified reference material (CRM), Scopolamine Impurity 28 (R-Isomer) 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 Scopolamine Impurity 28 (R-Isomer) HCl (CAS 64069-63-2 (free base)), a pharmacopoeial impurity reference standard (molecular formula C17H21NO4HCl, MW 339.82 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Scopolamine Impurity 28 (R-Isomer) HCl is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 339.82 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.
