1-(5-Chloro-2-methylthiophen-3-yl)ethanone CAS 98550-85-7

Description

The occurrence of 1-(5-Chloro-2-methylthiophen-3-yl)ethanone 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-(5-Chloro-2-methylthiophen-3-yl)ethanone (CAS 98550-85-7), molecular formula C7H7ClOS and molecular weight 174.65 g/mol, is a CATO reference standard with documented purity and traceability.

1-(5-Chloro-2-methylthiophen-3-yl)ethanone (C7H7ClOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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-(5-Chloro-2-methylthiophen-3-yl)ethanone 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.
