Industrial Applications of SODIUM 4-TOLUENESULFINATE HYDRATE
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Key intermediate in the synthesis of antifungal agents (e.g., terbinafine) | Undergoes nucleophilic substitution with haloalkanes to form carbon–sulfur bonds |
| Agrochemical Intermediates | Side-chain building block for sulfonylurea herbicides (e.g., bispyribac-sodium) | Acts as a sulfinyl group donor in condensation reactions |
| Dye Industry | Stabilizer for diazo components and reducing agent in azo dye synthesis | Regulates pH and suppresses side reactions during diazotization |
| Organic Synthesis | Precursor to chiral catalyst ligands (e.g., for asymmetric oxidation reactions) | Oxidized or coordinated to yield chiral sulfoxide ligands |
Manufacturing Quality Control of SODIUM 4-TOLUENESULFINATE HYDRATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (NaC7H7SO2.2H2O) | Acid-Base Titration | Quantifies active ingredient by titration with standardized HCl after acid hydrolysis and iodometric back-titration. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric reaction of iodine with water in anhydrous methanol medium. |
| pH (1% aqueous solution) | Potentiometric pH Measurement | Determines hydrogen ion activity using calibrated glass electrode in a 1% w/v aqueous solution. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomization and absorption measurement at characteristic wavelengths after acid digestion. |
| Sulfate (SO4) Impurity | Gravimetric Analysis | Precipitates sulfate as BaSO4 under controlled conditions and determines mass after ignition. |
| Chloride (Cl) Impurity | Potentiometric Titration with AgNO3 | Measures chloride by argentometric titration using silver nitrate and a silver indicator electrode. |
| Iron (Fe) Impurity | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Detects trace iron by plasma excitation and emission intensity measurement at Fe-specific wavelengths. |
| Loss on Drying (LOD) | Thermogravimetric Analysis (TGA) | Determines volatile content by measuring mass loss upon heating to 105 C under controlled atmosphere. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing at 600 C. |
| Appearance (Color & Clarity) | Visual Inspection | Assesses physical state, color, and presence of visible particulates or cloudiness against standard white background. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution by analyzing angular scattering pattern of laser light passing through dispersed sample. |
| Organic Impurities (related substances) | High Performance Liquid Chromatography (HPLC) | Separates and quantifies impurities using reversed-phase column and UV detection at 254 nm. |
