| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Intermediate in the synthesis of antitumor agents, antiviral agents, and nonsteroidal anti-inflammatory drugs | Used to introduce active molecular structures via acylation, condensation, or coupling reactions |
| Pesticides | Pre-cursor for active ingredients in fungicides and insecticides | Applied to construct heterocyclic pesticide molecular frameworks via substitution or cyclization reactions |
| Dyes and Pigments | Intermediate in the synthesis of organic dyes (e.g., sulfur dyes) | Involved in key dye synthesis steps such as diazotization and coupling |
| Analytical Chemistry | Colorimetric reagent or chelating agent for metal ions (e.g., copper, mercury) | Used to form colored metal complexes with metal ions via its amino and carboxyl groups for colorimetric analysis |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching with reference standards or relative response factors. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to react stoichiometrically with water in the sample dissolved in suitable anhydrous solvent. |
| Residue on Ignition | Gravimetric Analysis | Heating sample at 700-800 C to constant weight; residue mass expressed as percentage of original sample weight. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Atomic absorption spectroscopy after acid digestion; measures absorbance of ground-state atoms at element-specific wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation of chloride ions on an anion-exchange column with conductivity detection, quantified against calibration standards. |
| Sulfate Impurity | Ion Chromatography | Anion-exchange separation followed by suppressed conductivity detection; quantified using external calibration curve. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature range over which solid-to-liquid phase change occurs. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Measurement of hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using calibrated glass electrode system. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying | Weight loss measured after drying under specified conditions (e.g., 105 C, 2 h); reported as % w/w. |
| Organic Volatile Impurities | GC-FID | Separation by gas chromatography followed by flame ionization detection; quantified using internal or external standard method. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering pattern from dispersed particles to calculate volume-based size distribution. |
