Chemical Structure

Pramipexole EP Impurity A CAS 106092-09-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Pramipexole EP Impurity A.

CATO supplies Pramipexole EP Impurity A (CAS 106092-09-5), a pharmacopoeial impurity reference standard (molecular formula C7H11N3S, MW 169.25 g/mol) used for the identification and quantification of trace impurities in APIs.

Pramipexole EP Impurity A (C7H11N3S) contains a nitrile group, sulfur-containing functionality, an aromatic ring system. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 A 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.
