Industrial Applications of 938063-63-9
| Industry | Application | Process |
|---|---|---|
| Pesticides | Insecticide intermediate | Used in the synthesis of novel pyrethroid insecticides; serves as a thioester structural unit in cyclization or coupling reactions to construct sulfur-containing heterocycles or modify side chains |
| Pharmaceuticals | Drug synthesis intermediate | Acts as a sulfur-containing flexible linker in anti-inflammatory or antitumor candidate compounds; incorporated into active molecular scaffolds via ester hydrolysis, amidation, or Michael addition |
| Materials Science | Functional polymer monomer | Integrated into polymer backbones or side chains via free-radical polymerization or condensation polymerization to impart photoresponsiveness or metal-coordination capability; typically requires prior hydrolysis to the carboxylic acid followed by esterification or amidation for modification |
Manufacturing Quality Control of 938063-63-9
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase chromatography with UV detection at 210-230 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., starting materials, intermediates, degradation products) using gradient HPLC separation and UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, toluene, ethyl acetate) by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration where iodine reacts stoichiometrically with water in a pyridine-methanol solvent system. |
| Acid Value | Acid-Base Titration | Measures free carboxylic acid groups by titration with standardized potassium hydroxide solution using phenolphthalein or potentiometric endpoint detection. |
| Heavy Metals (as Pb) | ICP-OES | Quantifies total heavy metals (Pb, Cd, Hg, As, Cr) after acid digestion by measuring atomic emission intensities at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with suppressed conductivity detection after aqueous extraction. |
| Sulfur Content | Combustion IC | Determines total organic sulfur by high-temperature combustion followed by ion chromatographic detection of sulfate ions. |
| Optical Rotation | [alpha]D Measurement | Measures specific rotation using sodium D-line light to assess chiral purity and identity of the enantiomerically enriched compound. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating crystallinity and presence of impurities. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content after high-temperature incineration and weighing of residual non-volatile material. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of sample against established reference standards under controlled lighting conditions. |
