Compared with other compounds in its class, the molecular weight of 149.19 g/mol gives Prilocaine Impurity 15 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Prilocaine Impurity 15 (CAS 5602-96-0), a pharmacopoeial impurity reference standard (molecular formula C9H11NO, MW 149.19 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Prilocaine Impurity 15 (C9H11NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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 149.19 g/mol, it falls into the low-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
