Industrial Applications of 4-NITROBENZENESULFONYL FLUORIDE
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Key chiral building block for the synthesis of the antiplatelet drug ticagrelor | Used as a chiral sulfonyl fluoride auxiliary in stereoselective C–N bond formation via asymmetric reduction, amination, and coupling reactions |
| Pesticide Development | Structural modification precursor for novel sulfonyl fluoride insecticides/fungicides | Applied to introduce the –SO₂F group, enhancing covalent binding affinity with target proteins (e.g., GABA receptors or chitin synthase) |
| Materials Science | Crosslinking monomer for fluorinated functional polymers | Undergoes sulfonyl fluoride–amine click chemistry (SuFEx) with olefin- or amine-containing polymers under radical or thermal initiation to produce weather-resistant coatings or ion-exchange membranes |
Manufacturing Quality Control of 4-NITROBENZENESULFONYL FLUORIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-DAD | Separation and identification of impurities using gradient HPLC with diode-array detection; relative retention times and spectral matching used for qualification. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents based on calibrated response factors. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to react stoichiometrically with water; endpoint detected amperometrically. |
| Acid Value | Acid-Base Titration | Neutralization of acidic impurities with standardized sodium hydroxide solution using phenolphthalein indicator or potentiometric endpoint detection. |
| Residue on Ignition | Gravimetric Analysis | Weighing of non-volatile residue remaining after controlled high-temperature ashing of sample in a platinum crucible. |
| Heavy Metals | ICP-OES | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, based on element-specific atomic emission intensities. |
| Chloride Content | Ion Chromatography | Separation and quantification of chloride anions using anion-exchange column and suppressed conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature range using calibrated capillary apparatus under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of the solid material against standard white background under controlled lighting. |
| Bulk Density | Graduated Cylinder Method | Calculation of mass per unit volume after gentle tapping of a known mass of powder into a calibrated cylinder. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as a function of angle to determine volume-based particle size distribution. |
