Meropenem Impurity 64 CAS 54238-00-5

Description

Compared with other compounds in its class, the molecular weight of 119.16 g/mol gives Meropenem Impurity 64 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Meropenem Impurity 64 (CAS 54238-00-5) is a certified pharmaceutical impurity reference standard with the molecular formula C8H9N and a molecular weight of 119.16 g/mol.

Structurally, Meropenem Impurity 64 (C8H9N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 119.16 g/mol, it falls into the low-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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
