Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 293.27 g/mol gives Nimodipine Impurity 54 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Nimodipine Impurity 54 (CAS CATO-C4X-138554), a pharmacopoeial impurity reference standard (molecular formula C14H15NO6, MW 293.27 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Nimodipine Impurity 54 (C14H15NO6) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 293.27 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
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.
