Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (3-Fluoro-phenyl)-methanesulfonyl chloride (3-fluorophenyl)methanesulfonyl chloride (3-fluorophenyl)methanesulphonyl chloride 24974-72-9 3-(fluorophenyl)methanesulfonyl chloride 3-fluorobenzylsulphonyl chloride benzenemethanesulfonyl chloride, 3-fluoro-.
(3-Fluoro-phenyl)-methanesulfonyl chloride (3-fluorophenyl)methanesulfonyl chloride (3-fluorophenyl)methanesulphonyl chloride 24974-72-9 3-(fluorophenyl)methanesulfonyl chloride 3-fluorobenzylsulphonyl chloride benzenemethanesulfonyl chloride, 3-fluoro- (CAS 24974-72-9), molecular formula C7H6ClFO2S and molecular weight 208.64 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (3-Fluoro-phenyl)-methanesulfonyl chloride (3-fluorophenyl)methanesulfonyl chloride (3-fluorophenyl)methanesulphonyl chloride 24974-72-9 3-(fluorophenyl)methanesulfonyl chloride 3-fluorobenzylsulphonyl chloride benzenemethanesulfonyl chloride, 3-fluoro- (C7H6ClFO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 208.64 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
