Chemical Structure

Pramipexole Impurity 44 CAS 1001648-65-2 chemical structure

Description

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.

Pramipexole Impurity 44 (CAS 1001648-65-2) is a certified pharmaceutical impurity reference standard with the molecular formula C7H11N3OS and a molecular weight of 185.25 g/mol.

Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, Pramipexole Impurity 44 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 185.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

CATO manufactures Pramipexole Impurity 44 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
