1-(4-Bromothiophen-2-yl)-2,2-dimethylpropan-1-one (CAS 33148-68-4), molecular formula C9H11BrOS and molecular weight 247.15 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(4-Bromothiophen-2-yl)-2,2-dimethylpropan-1-one (C9H11BrOS) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
