Description
As a certified reference material (CRM), 3-Bromobenzothiophene 1,1-Dioxide 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.
3-Bromobenzothiophene 1,1-Dioxide (CAS 16957-97-4) is a high-purity analytical reference standard with the molecular formula C8H5BrO2S and a molecular weight of 245.09 g/mol.
The molecular framework of 3-Bromobenzothiophene 1,1-Dioxide (C8H5BrO2S) is characterized by a sulfone group, a carboxylic acid group, 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.
