Chemical Structure
Description
The molecular framework of 1,3-Dichloro-4,5,6,7-tetrahydro-2-benzothiophen-4-one (C8H6Cl2OS) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
1,3-Dichloro-4,5,6,7-tetrahydro-2-benzothiophen-4-one (CAS 35061-13-3), molecular formula C8H6Cl2OS and molecular weight 221.10 g/mol, is a CATO reference standard with documented purity and traceability.
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-Dichloro-4,5,6,7-tetrahydro-2-benzothiophen-4-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.
