Chemical Structure

1-(3-Chlorophenyl)-2-(ethylthio)propan-1-one CAS 1157221-88-9 chemical structure

Description

Based on its molecular formula C11H13ClOS, 1-(3-Chlorophenyl)-2-(ethylthio)propan-1-one contains sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 228.74 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.

1-(3-Chlorophenyl)-2-(ethylthio)propan-1-one (CAS 1157221-88-9) is a high-purity analytical reference standard with the molecular formula C11H13ClOS and a molecular weight of 228.74 g/mol.

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.
