CATO supplies Teneligliptin Impurity 4 (CAS 401566-80-1), a pharmacopoeial impurity reference standard (molecular formula C27H38N6O3S, MW 526.69 g/mol) used for the identification and quantification of trace impurities in APIs.
Teneligliptin Impurity 4 (C27H38N6O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
