Chemical Structure
Description
The occurrence of 1-(3-Chlorophenyl)-2-(methylthio)ethan-1-one is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(3-Chlorophenyl)-2-(methylthio)ethan-1-one (CAS 122831-54-3) is a high-purity analytical reference standard with the molecular formula C9H9ClOS and a molecular weight of 200.69 g/mol.
The molecular framework of 1-(3-Chlorophenyl)-2-(methylthio)ethan-1-one (C9H9ClOS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 manufactures 1-(3-Chlorophenyl)-2-(methylthio)ethan-1-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
