Chemical Structure

1-(2-Chloro-3-methyl-4-(methylthio)phenyl)ethanone CAS 181997-71-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 214.71 g/mol gives 1-(2-Chloro-3-methyl-4-(methylthio)phenyl)ethanone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-(2-Chloro-3-methyl-4-(methylthio)phenyl)ethanone (CAS 181997-71-7) is a high-purity analytical reference standard with the molecular formula C10H11ClOS and a molecular weight of 214.71 g/mol.

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 1-(2-Chloro-3-methyl-4-(methylthio)phenyl)ethanone is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 214.71 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 1-(2-Chloro-3-methyl-4-(methylthio)phenyl)ethanone meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
