Chemical Structure
Description
The occurrence of 3-Chloro-2-fluorobenzenethiol is closely related to sulfur-containing functionality, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Chloro-2-fluorobenzenethiol (CAS 1121585-29-2), molecular formula C6H4ClFS and molecular weight 162.61 g/mol, is a CATO reference standard with documented purity and traceability.
3-Chloro-2-fluorobenzenethiol (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. 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.
As a certified reference material (CRM), 3-Chloro-2-fluorobenzenethiol 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.
