Pinaverium Bromide Impurity 44 CAS 87325-77-7

Description

The occurrence of Pinaverium Bromide Impurity 44 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Pinaverium Bromide Impurity 44 (CAS 87325-77-7) is a certified pharmaceutical impurity reference standard with the molecular formula C9H8Br4O2 and a molecular weight of 467.77 g/mol.

Structurally, Pinaverium Bromide Impurity 44 (C9H8Br4O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 467.77 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Pinaverium Bromide Impurity 44 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.
