1-Hydroxy-5,5-dimethyl-2-phenylimidazolidine-4-thione CAS 257869-91-3

Description

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.

CATO supplies 1-Hydroxy-5,5-dimethyl-2-phenylimidazolidine-4-thione (CAS 257869-91-3), a certified reference material (molecular formula C11H14N2OS, MW 222.31 g/mol) for analytical method development and quality control.

Based on its molecular formula C11H14N2OS, 1-Hydroxy-5,5-dimethyl-2-phenylimidazolidine-4-thione contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 222.31 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
