| Industry | Application | Process |
|---|---|---|
| Pesticides | Herbicide synthesis | Used as an intermediate in the synthesis of specific herbicides, including certain selective herbicides. |
| Pharmaceuticals | Drug intermediate synthesis | Applied as a key intermediate in the synthesis of certain pharmaceuticals to construct complex molecular frameworks. |
| Research Institutions | Chemical research | Employed as an important reagent or model compound in organic synthesis research to support exploration of novel synthetic routes or reaction mechanisms. |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorption at specific wavelength using reverse-phase chromatography with external standard calibration. |
| Related Substances | HPLC-DAD | Detects and quantifies impurities and degradation products via UV spectral comparison and peak area integration against reference standards. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., ethanol, ethyl acetate) using flame ionization detection after headspace or direct injection. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration based on iodine consumption in a pyridine-methanol solvent system. |
| Heavy Metals | ICP-OES | Quantifies elemental impurities (e.g., Pb, Cd, Hg, As) after acid digestion using plasma excitation and atomic emission spectroscopy. |
| Chloride Content | Potentiometric Titration | Measures chloride ions using silver nitrate titrant and silver/silver chloride indicator electrode for endpoint detection. |
| Acid Value | Acid-Base Titration | Determines free carboxylic acid groups by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content by high-temperature incineration followed by precise weighing of residual residue. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method per USP/Ph.Eur. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of sample against specified criteria under controlled lighting and white background. |
| Specific Optical Rotation | Polarimetry | Measures chiral purity by detecting rotation of plane-polarized light in solution using sodium D-line illumination. |
| Particle Size Distribution | Laser Diffraction | Determines granulometric profile by analyzing angular scattering pattern of laser beam passing through dispersed sample. |
