Chemical Structure
Description
As a certified reference material (CRM), Teneligliptin impurity 21 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 Teneligliptin impurity 21 (CAS 2459971-79-8), a pharmacopoeial impurity reference standard (molecular formula C45H60N12O2S2, MW 865.17 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, Teneligliptin impurity 21 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 865.17 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).
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.
