Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (3,4-Difluorobenzyl)(3,4-difluorophenyl)sulfane.
(3,4-Difluorobenzyl)(3,4-difluorophenyl)sulfane (CAS 1443347-43-0) is a high-purity analytical reference standard with the molecular formula C13H8F4S and a molecular weight of 272.26 g/mol.
(3,4-Difluorobenzyl)(3,4-difluorophenyl)sulfane (C13H8F4S) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures (3,4-Difluorobenzyl)(3,4-difluorophenyl)sulfane under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
