Pramipexole EP Impurity D HCl CAS 1332889-14-1

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 D HCl.

CATO supplies Pramipexole EP Impurity D HCl (CAS 1332889-14-1), a pharmacopoeial impurity reference standard (molecular formula C10H17N3SHCl, MW 247.78 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C10H17N3SHCl, Pramipexole EP Impurity D HCl contains a nitrile group, sulfur-containing functionality, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 247.78 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
