4-Acetyl-2-((benzylthio)methyl)-5-hydroxy-1-methyl-1H-pyrrol-3(2H)-one CAS 735-18-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Acetyl-2-((benzylthio)methyl)-5-hydroxy-1-methyl-1H-pyrrol-3(2H)-one.

4-Acetyl-2-((benzylthio)methyl)-5-hydroxy-1-methyl-1H-pyrrol-3(2H)-one (CAS 735-18-2), molecular formula C15H17NO3S and molecular weight 291.37 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C15H17NO3S, 4-Acetyl-2-((benzylthio)methyl)-5-hydroxy-1-methyl-1H-pyrrol-3(2H)-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 291.37 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
