Chemical Structure
Description
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.
CATO supplies Pramipexole impurity 79 (CAS CATO-C4X-110779), a pharmacopoeial impurity reference standard (molecular formula C20H31N7OS2, MW 449.64 g/mol) used for the identification and quantification of trace impurities in APIs.
Pramipexole impurity 79 (C20H31N7OS2) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; 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).
As a certified reference material (CRM), Pramipexole impurity 79 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.
