Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2,5-Difluorobenzyl)(3-fluorophenyl)sulfane.
(2,5-Difluorobenzyl)(3-fluorophenyl)sulfane (CAS 1443312-72-8) is a high-purity analytical reference standard with the molecular formula C13H9F3S and a molecular weight of 254.27 g/mol.
(2,5-Difluorobenzyl)(3-fluorophenyl)sulfane (C13H9F3S) contains sulfur-containing functionality, 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 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
