2-Acetyl-4,5-dibromothiophene (CAS 7209-12-3) is a high-purity analytical reference standard with the molecular formula C6H4Br2OS and a molecular weight of 283.97 g/mol.
The molecular framework of 2-Acetyl-4,5-dibromothiophene (C6H4Br2OS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine 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).
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 2-Acetyl-4,5-dibromothiophene 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.
