Industrial Applications of methyl 2-ethoxycarbothioylsulfanylpropanoate
| Industry | Application | Process |
|---|---|---|
| Pesticides | Insecticide intermediate | Serves as a key structural building block for synthesizing novel neonicotinoid insecticides (e.g., flupyradifurone), enabling thiazoline ring formation via cyclization involving the thiocarbonyl group |
Manufacturing Quality Control of methyl 2-ethoxycarbothioylsulfanylpropanoate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area comparison against certified reference standard. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies impurities based on mass spectral fragmentation patterns and retention behavior. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Measures water via electrochemical iodine generation and stoichiometric reaction with water in anhydrous methanol medium. |
| Residue on Ignition | Gravimetric analysis after high-temperature ashing | Determines non-volatile inorganic residue by weight difference before and after ignition at 700-800 C. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantifies total heavy metals by atomic emission intensity of metal-specific wavelengths in plasma-excited sample aerosol. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separates and quantifies chloride ions using anion-exchange column and suppressed conductivity detection. |
| Acid Value | Acid-base titration with standardized NaOH solution | Measures free acid content by neutralization with NaOH using phenolphthalein endpoint detection. |
| Specific Optical Rotation | Polarimetry | Determines chiral purity by measuring angular rotation of plane-polarized light passing through a solution of the compound. |
| Density | Oscillating U-tube densitometry | Calculates density from resonant frequency shift of a vibrating U-shaped glass tube filled with sample. |
| Refractive Index | Refractometry (Abbe type) | Measures ratio of light velocity in air versus sample using critical angle of total internal reflection. |
| Appearance | Visual inspection in clear glass container under controlled lighting | Evaluates physical state, color, and clarity against established visual standards for liquid organic chemicals. |
| pH of Aqueous Solution (1% w/v) | Potentiometric pH measurement with calibrated electrode | Determines hydrogen ion activity in aqueous dispersion using glass electrode and reference electrode system. |
