Chemical Structure

3,5-Difluorothiophenol CAS 845823-02-1 chemical structure

Description

As a certified reference material (CRM), 3,5-Difluorothiophenol 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.

3,5-Difluorothiophenol (CAS 845823-02-1) is a high-purity analytical reference standard with the molecular formula C6H4ClFS and a molecular weight of 162.61 g/mol.

3,5-Difluorothiophenol (C6H4ClFS) contains sulfur-containing functionality, fluorine/chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
