The occurrence of 4-Methylsulfonyl-2-nitrofluorobenzene 2-fluoro-5-methylsulphonyl nitrobenzene 1-fluoro-4-methanesulfonyl-2-nitro-benzene 2-fluoro-5-methylsulfonylnitrobenzene 1-fluoro-4-methylsulfonyl-2-nitrobenzene 2-fluoro-5-methyl sulfonyl nitrobenzene 1-fluoro-4-(methylsulfonyl)-2-nitrobenzene 2-fluoro-5-methylsulphonylnitrobenzene 1-fluoro-4-(methylsulphonyl)-2-nitrobenzene (3-Nitro-4-fluorophenyl)methyl sulfone 1-Fluoro-4-methanesulfonyl-2-nitrobenzene 4-Fluoro-3-nitrophenyl methyl sulfone 453-72-5 is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-Methylsulfonyl-2-nitrofluorobenzene 2-fluoro-5-methylsulphonyl nitrobenzene 1-fluoro-4-methanesulfonyl-2-nitro-benzene 2-fluoro-5-methylsulfonylnitrobenzene 1-fluoro-4-methylsulfonyl-2-nitrobenzene 2-fluoro-5-methyl sulfonyl nitrobenzene 1-fluoro-4-(methylsulfonyl)-2-nitrobenzene 2-fluoro-5-methylsulphonylnitrobenzene 1-fluoro-4-(methylsulphonyl)-2-nitrobenzene (3-Nitro-4-fluorophenyl)methyl sulfone 1-Fluoro-4-methanesulfonyl-2-nitrobenzene 4-Fluoro-3-nitrophenyl methyl sulfone 453-72-5 (CAS 453-72-5), a certified reference material (molecular formula C7H12FNO4S, MW 225.24 g/mol) for analytical method development and quality control.
4-Methylsulfonyl-2-nitrofluorobenzene 2-fluoro-5-methylsulphonyl nitrobenzene 1-fluoro-4-methanesulfonyl-2-nitro-benzene 2-fluoro-5-methylsulfonylnitrobenzene 1-fluoro-4-methylsulfonyl-2-nitrobenzene 2-fluoro-5-methyl sulfonyl nitrobenzene 1-fluoro-4-(methylsulfonyl)-2-nitrobenzene 2-fluoro-5-methylsulphonylnitrobenzene 1-fluoro-4-(methylsulphonyl)-2-nitrobenzene (3-Nitro-4-fluorophenyl)methyl sulfone 1-Fluoro-4-methanesulfonyl-2-nitrobenzene 4-Fluoro-3-nitrophenyl methyl sulfone 453-72-5 (C7H12FNO4S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
