Ampicillin Impurity 96 CAS 35039-72-6

Description

Compared with other compounds in its class, the molecular weight of 269.30 g/mol gives Ampicillin Impurity 96 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ampicillin Impurity 96 (CAS 35039-72-6) is a certified pharmaceutical impurity reference standard with the molecular formula C16H15NO3 and a molecular weight of 269.30 g/mol.

Structurally, Ampicillin Impurity 96 (C16H15NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 269.30 g/mol, it falls into the medium-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.

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), Ampicillin Impurity 96 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.
