| Industry | Application | Process |
|---|---|---|
| Pesticides | Synthesis of pesticide intermediates for novel herbicides and fungicides | Electrophilic substitution on the aromatic ring to introduce fluorine and nitro groups, followed by oxidation to generate carboxylic acid |
| Pharmaceuticals | Drug synthesis intermediate for anti-inflammatory and antitumor agents | Reduction of nitro to amino group, followed by coupling or acylation to construct the drug scaffold |
| High-performance polymers | Synthesis of monomers for high-performance polymers, such as high-temperature engineering plastics | Esterification or amidation to prepare functional monomers, which participate in condensation or addition polymerization |
| Dyes and pigments | Dye intermediate for producing fluorinated and nitrated organic dyes | Diazotization-coupling to construct chromophores, enhancing dye stability and color performance |
| Electronic chemicals | Production of liquid crystal materials or photoresist components for semiconductors | Fluorination and nitration to optimize molecular polarity and thermal stability, meeting electronic-grade purity requirements |
| 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 and threshold limits per ICH Q3A. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., methanol, acetone, DMF) against calibrated standards. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration measuring water content via iodine-sulfur dioxide reaction in anhydrous methanol-based medium. |
| Heavy Metals | ICP-MS | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion and dilution, per USP <233>. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using suppressed conductivity detection after aqueous extraction. |
| Sulfated Ash | Gravimetric Analysis | Ignition at 700-800 C followed by weighing of non-volatile residue after sulfuric acid treatment. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white light against established reference samples. |
| Particle Size Distribution | Laser Diffraction | Dry dispersion and size analysis based on light scattering patterns measured across a defined angular range. |
| Acid Value | Acid-Base Titration | Neutralization of carboxylic acid groups with standardized NaOH solution using phenolphthalein indicator. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution in a sodium D-line lamp cell, corrected for concentration and path length. |
