Description
As a certified reference material (CRM), 5'-Fluoro-2'-methyl-[1,1'-biphenyl]-3-thiol 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.
5'-Fluoro-2'-methyl-[1,1'-biphenyl]-3-thiol (CAS 1443327-40-9), molecular formula C13H11FS and molecular weight 218.29 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, fluorine substitution, an aromatic ring system, 5'-Fluoro-2'-methyl-[1,1'-biphenyl]-3-thiol is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 218.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
