Chemical Structure

5'-Fluoro-2'-methoxy-[1,1'-biphenyl]-4-thiol CAS 1443305-90-5 chemical structure

Description

5'-Fluoro-2'-methoxy-[1,1'-biphenyl]-4-thiol (CAS 1443305-90-5) is a high-purity analytical reference standard with the molecular formula C13H11FOS and a molecular weight of 234.29 g/mol.

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 5'-Fluoro-2'-methoxy-[1,1'-biphenyl]-4-thiol is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 234.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 5'-Fluoro-2'-methoxy-[1,1'-biphenyl]-4-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.
