(2-FLUOROPHENYL)METHANESULFONYL CHLORIDE (2-FLUOROPHENYL)METHANESULPHONYL CHLORIDE 2-(Fluorophenyl)methanesulfonyl chloride 24974-71-8 ALPHA-(CHLOROSULPHONYL)-2-FLUOROTOLUENE AS05027 BENZENEMETHANESULFONYL CHLORIDE, 2-FLUORO- CHLORO[(2-FLUOROPHENYL)METHYL]SULFONE (CAS 24974-71-8) is a high-purity analytical reference standard with the molecular formula C7H6ClFO2S and a molecular weight of 208.64 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, (2-FLUOROPHENYL)METHANESULFONYL CHLORIDE (2-FLUOROPHENYL)METHANESULPHONYL CHLORIDE 2-(Fluorophenyl)methanesulfonyl chloride 24974-71-8 ALPHA-(CHLOROSULPHONYL)-2-FLUOROTOLUENE AS05027 BENZENEMETHANESULFONYL CHLORIDE, 2-FLUORO- CHLORO[(2-FLUOROPHENYL)METHYL]SULFONE is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 208.64 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
