Chemical Structure

Piperazine Impurity 5 CAS 120975-07-7 chemical structure

Description

Structurally, Piperazine Impurity 5 (C17H20N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 252.35 g/mol, it falls into the medium-molecular-weight range. 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 supplies Piperazine Impurity 5 (CAS 120975-07-7), a pharmacopoeial impurity reference standard (molecular formula C17H20N2, MW 252.35 g/mol) used for the identification and quantification of trace impurities in APIs.

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.

As a certified reference material (CRM), Piperazine Impurity 5 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.
