Chemical Structure
Description
The occurrence of 3,5-Difluoro-4-propoxybenzenethiol is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3,5-Difluoro-4-propoxybenzenethiol (CAS 1379356-05-4), molecular formula C9H10F2OS and molecular weight 204.24 g/mol, is a CATO reference standard with documented purity and traceability.
3,5-Difluoro-4-propoxybenzenethiol (C9H10F2OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine 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.
As a certified reference material (CRM), 3,5-Difluoro-4-propoxybenzenethiol 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.
