(3,4-Difluorobenzyl)(3-fluorophenyl)sulfane CAS 1443336-92-2

Description

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-fluorophenyl)sulfane.

(3,4-Difluorobenzyl)(3-fluorophenyl)sulfane (CAS 1443336-92-2), molecular formula C13H9F3S and molecular weight 254.27 g/mol, is a CATO reference standard with documented purity and traceability.

(3,4-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 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.

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.
