Chemical Structure

Brexpiprazole Impurity 11 CAS 2250242-22-7 chemical structure

Description

Structurally, Brexpiprazole Impurity 11 (C28H34N4S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 490.73 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Brexpiprazole Impurity 11 (CAS 2250242-22-7) is a certified pharmaceutical impurity reference standard with the molecular formula C28H34N4S2 and a molecular weight of 490.73 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), Brexpiprazole Impurity 11 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.
