| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Used as an organic synthesis intermediate for the production of anti-inflammatory agents, antimicrobial agents, and other active pharmaceutical ingredients (APIs) | Participates in drug molecule construction via esterification, amidation, or nucleophilic substitution reactions |
| Pesticides | Used as a pesticide intermediate for the synthesis of herbicides or fungicides | Introduces heterocyclic structures through diazotization, coupling, or cyclization steps |
| Dyes & Pigments | Used as an intermediate for azo dyes or functional dyes | Participates in diazotization and coupling reactions to generate colored compounds |
| Fine Chemicals | Used to synthesize functional chemicals such as fragrances and UV absorbers | Prepares target products via organic transformation reactions including alkylation, condensation, or oxidation |
| 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. |
| Residual Solvents | GC-FID | Detection and quantification of volatile organic solvents (e.g., methanol, toluene) using gas chromatography with flame ionization detection and external calibration. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma mass spectrometry for ultra-trace sensitivity. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration with iodine-based reagent to determine trace water content based on stoichiometric reaction with water. |
| Acid Value | Acid-Base Titration | Titration with standardized sodium hydroxide solution using phenolphthalein indicator to quantify free carboxylic acid groups. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of the solid sample against established visual reference standards under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, using calibrated capillary apparatus per USP <741>. |
| Residue on Ignition | Gravimetric Analysis | Weighing residue remaining after high-temperature ashing (600-800 C) to assess inorganic impurities and non-volatile residues. |
| Chloride Content | Ion Chromatography | Separation and quantification of chloride ions in aqueous extract using suppressed conductivity detection and external calibration. |
| Particle Size Distribution | Laser Diffraction | Measurement of particle size distribution in dry powder form using Mie theory-based laser diffraction analysis. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution to confirm chiral integrity and absence of racemization. |
