Description
As a certified reference material (CRM), 3,4-Difluoro-5-(pentyloxy)benzenethiol 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.
3,4-Difluoro-5-(pentyloxy)benzenethiol (CAS 1443310-59-5) is a high-purity analytical reference standard with the molecular formula C11H14F2OS and a molecular weight of 232.29 g/mol.
3,4-Difluoro-5-(pentyloxy)benzenethiol (C11H14F2OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
