Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (S)-5-(4-Hydroxybenzyl)-2-thioxoimidazolidin-4-one (CAS 34273-45-5), a certified reference material (molecular formula C10H10N2O2S, MW 222.26 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H10N2O2S, (S)-5-(4-Hydroxybenzyl)-2-thioxoimidazolidin-4-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 222.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
