Compared with other compounds in its class, the molecular weight of 211.33 g/mol gives Pramipexole EP Impurity D distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Pramipexole EP Impurity D (CAS 104632-28-2), a pharmacopoeial impurity reference standard (molecular formula C10H17N3S, MW 211.33 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, Pramipexole EP Impurity D is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 211.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
As a certified reference material (CRM), Pramipexole EP Impurity D 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.
