Chemical Structure
Description
(3-(Bromomethyl)-5-chlorophenyl)pentafluoro-lambda6-sulfane (C7H5BrClF5S) contains sulfur-containing functionality, fluorine/chlorine/bromine substitution. 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.
(3-(Bromomethyl)-5-chlorophenyl)pentafluoro-lambda6-sulfane (CAS 1240257-05-9), molecular formula C7H5BrClF5S and molecular weight 331.53 g/mol, is a CATO reference standard with documented purity and traceability.
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.
