Chemical Structure

Penicillamine Impurity 1 CAS 4458-32-6 chemical structure

Description

Structurally, Penicillamine Impurity 1 (C6H15N) contains an organic framework. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 101.19 g/mol, it falls into the low-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Penicillamine Impurity 1 (CAS 4458-32-6) is a certified pharmaceutical impurity reference standard with the molecular formula C6H15N and a molecular weight of 101.19 g/mol.

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), Penicillamine Impurity 1 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.
