Industrial Applications of 2,3-Difluoro-6-nitroaniline
| Industry | Application | Process |
|---|---|---|
| Agrochemicals | Key intermediate in the synthesis of the insecticide/acaricide bifenazate | Constructs the benzidine moiety of bifenazate via diazotization, reduction, or coupling reactions |
| Pharmaceuticals | Fluorinated building block for drug molecules | Enables further functional group transformations—leveraging fluorine’s properties and the reactivity of nitro and amino groups—to synthesize drug candidates |
Manufacturing Quality Control of 2,3-Difluoro-6-nitroaniline
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at ~254 nm. |
| Related Substances | HPLC-UV or UPLC-UV | Separation and quantification of structurally related impurities (e.g., isomers, reduction by-products, residual nitro precursors) using gradient elution and UV detection. |
| Residual Solvents | GC-FID or GC-MS | Headspace gas chromatography with flame ionization detection or mass spectrometry to quantify volatile organic solvents (e.g., DMF, toluene, methanol) per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration measuring water via iodine generation and stoichiometric reaction with water in anhydrous medium. |
| Heavy Metals | ICP-MS or ICP-OES | Quantification of elemental impurities (e.g., Pb, Cd, As, Hg) after acid digestion, based on atomic emission or mass spectral detection. |
| Residual Inorganic Salts (e.g., NaCl, FeCl₃) | Ion Chromatography (IC) or AAS | Anion/cation separation and quantification (IC) or atomic absorption measurement (AAS) for catalyst or workup residues. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition determination via controlled heating; deviation from literature value (108–110 °C) indicates impurity presence. |
| Appearance & Color | Visual Inspection / Hazen/APHA Color Scale | Subjective assessment of physical state (crystalline solid) and color intensity against platinum-cobalt standards. |
| Chloride Content | Potentiometric Titration (AgNO₃) | Precipitation titration using silver nitrate with silver indicator electrode to detect chloride ion concentration. |
| pH of Aqueous Suspension | pH Meter (10% w/v in water) | Measurement of surface proton activity in aqueous slurry, indicating residual acidic/basic process impurities. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to determine volumetric particle size distribution (D10, D50, D90). |
