Description
As a certified reference material (CRM), Amisulpride Impurity 29 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 Amisulpride Impurity 29 (CAS 148516-69-2), a pharmacopoeial impurity reference standard (molecular formula C10H13NO5S, MW 259.28 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Amisulpride Impurity 29 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 259.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
