Industrial Applications of 2-METHYL-2-THIOPSEUDOUREA,SULFATE
| Industry | Application | Process |
|---|---|---|
| Agrochemicals | Key intermediate in the synthesis of the insecticide methomyl | Reacted with acetaldehyde using S-methylisothiourea sulfate as the starting material to produce methylthioacetaldoxime, followed by methylation and carbamoylation |
| Agrochemicals | Intermediate in the synthesis of the insecticide thiodicarb | Used to construct the methylthioacetaldoxime structural unit via the methomyl synthesis pathway, starting from S-methylisothiourea sulfate |
| Pharmaceuticals | Synthetic raw material for the antithyroid drug thiamazole | Undergoes cyclization with chloroacetone or chloroacetaldehyde to form the thiol-containing imidazole ring |
| Pharmaceuticals | Reagent for synthesizing sulfonamide drugs and certain bioactive molecules | Serves as a guanylation or thiolation reagent to introduce functional groups during drug molecule construction |
| Dyes | Intermediate in the synthesis of cationic dyes | Acts as a sulfur-containing component in heterocyclic compound synthesis, participating in condensation and cyclization reactions of dye molecules |
| Chemical Synthesis | Preparation of downstream chemicals such as brominated S-methylisothiourea | Subjected to salt metathesis or exchange reactions with hydrobromic acid or bromide salts |
Manufacturing Quality Control of 2-METHYL-2-THIOPSEUDOUREA,SULFATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (S-Methylisothiourea Sulfate) | Acid-Base Titration | Quantifies active ingredient by titration with standardized NaOH after hydrolysis to liberate methylamine, using bromocresol green indicator. |
| Water Content | Karl Fischer Titration | Measures trace water via coulometric or volumetric reaction between water and iodine generated in situ from KF reagent. |
| pH (1% aqueous solution) | pH Meter Measurement | Determines hydrogen ion activity in a standardized aqueous solution using calibrated glass electrode pH meter. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomization and absorption measurement at characteristic wavelengths after acid digestion. |
| Sulfate Content | Gravimetric Analysis | Precipitates sulfate as BaSO4 under controlled conditions and determines mass after ignition and drying. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column with conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities by weight loss after high-temperature ashing at 700-800 C. |
| Related Substances | High Performance Liquid Chromatography (HPLC) | Separates and quantifies structural analogs and degradation products using reversed-phase C18 column and UV detection. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles against established reference standards under controlled lighting. |
| Solubility | Qualitative Solubility Test | Evaluates complete dissolution in specified solvents (e.g., water, methanol) at defined temperature and concentration. |
| Iron (Fe) Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantifies trace iron after microwave-assisted acid digestion by measuring element-specific emission intensities. |
| Loss on Drying | Thermogravimetric Analysis (TGA) | Determines volatile content by measuring mass loss upon heating to 105 C under controlled atmosphere for fixed duration. |
