Industrial Applications of 542-85-8
| Industry | Application | Process |
|---|---|---|
| Agriculture | Soil fumigant and insecticide | Applied as a pre-plant soil fumigation treatment, leveraging its volatility and biocidal activity against soil-borne pests (e.g., nematodes), fungi, and weed seeds |
| Agriculture | Pesticide intermediate | Used as a key raw material in the synthesis of dithiocarbamate fungicides or other sulfur-containing insecticides |
| Food Industry | Food additive (flavoring agent) | Added within established safety limits to seasonings, sauces, or savory foods to impart a pungent, mustard-like aroma |
| Pharmaceutical Industry | Pharmaceutical synthesis intermediate | Serves as a sulfur-functional group donor in the synthesis of bioactive heterocyclic compounds or drug precursors |
| Chemical Industry | Organic synthesis reagent | Utilized for its highly reactive isothiocyanate group (–N=C=S) to form thiourea derivatives with amines or to construct heterocyclic frameworks |
| Scientific Research | Chemical analytical reagent | Employed as a derivatization reagent in sequence analysis of amino acids, peptides, or proteins (e.g., analogous to Edman degradation) |
Manufacturing Quality Control of 542-85-8
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Acidity (as HCl) | Acid-Base Titration with NaOH and phenolphthalein indicator | Neutralization of acidic impurities by standardized sodium hydroxide solution; endpoint detected by color change. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Sample heated to 700-800 C in a platinum crucible; residue weight measured after cooling in desiccator. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after wet digestion | Sample digested with nitric and sulfuric acids; lead content quantified by AAS at 283.3 nm using air-acetylene flame. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separation of chloride anions on an anion-exchange column followed by quantitative detection via suppressed conductivity. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Comparison of sample color against APHA platinum-cobalt standards or measurement of absorbance at 455 nm in 1 cm cell. |
| Density at 20 C | Digital Density Meter (Oscillating U-tube principle) | Measurement of sample density based on resonant frequency shift of a vibrating U-shaped glass tube filled with sample. |
| Refractive Index at 20 C | Abbe Refractometer | Determination of refractive index by measuring critical angle of total internal reflection at the prism-sample interface. |
| Non-Volatile Residue | Gravimetric Evaporation | Sample evaporated to dryness at 105 C under controlled airflow; residue weighed after cooling in desiccator. |
| Aldehyde Impurity (e.g., acetaldehyde) | GC with Headspace Sampling and FID | Headspace equilibration followed by GC separation and FID detection; quantification using external calibration curve. |
| Odor Threshold (Qualitative) | Sensory Evaluation by Trained Panel | Organoleptic assessment by trained personnel to detect off-odor deviations from reference material under standardized conditions. |
