Description

Compared with other compounds in its class, the molecular weight of 318.39 g/mol gives 3-(Naphthalen-1-yl)-1-phenyl-2-thioxoimidazolidin-4-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-(Naphthalen-1-yl)-1-phenyl-2-thioxoimidazolidin-4-one (CAS 93286-14-7), molecular formula C19H14N2OS and molecular weight 318.39 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-(Naphthalen-1-yl)-1-phenyl-2-thioxoimidazolidin-4-one (C19H14N2OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
