Description
As a certified reference material (CRM), 6-[(3-bromophenyl)sulfanyl]pyridine-2-carboxylic acid 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.
6-[(3-bromophenyl)sulfanyl]pyridine-2-carboxylic acid (CAS 1282168-23-3), molecular formula C12H8BrNO2S and molecular weight 310.17 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-[(3-bromophenyl)sulfanyl]pyridine-2-carboxylic acid (C12H8BrNO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
