| Industry | Application | Process Description |
|---|---|---|
| Pharmaceuticals | Synthetic intermediate for active pharmaceutical ingredients (APIs) | Used as an intermediate in the synthesis of anti-inflammatory, antimicrobial, or antitumor agents |
| Agrochemicals | Synthesis of insecticides and herbicides | Employed as a fluorinated organic compound in the preparation of insecticides or herbicides |
| Chemical Industry | Raw material for organic synthesis | Used to synthesize other fluorinated aromatic compounds |
| Materials Science | Synthesis of functional materials | Applied as a structural unit in liquid crystal materials or specialty polymeric materials |
| Research | Analytical reagent and reference standard | Used in organic synthesis research or as an analytical reference standard |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at ~220–254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV or UPLC-UV | Separation and quantification of impurities (e.g., starting materials, intermediates, degradation products) using gradient HPLC/UPLC with UV detection and relative response factor correction. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify volatile organic solvents (e.g., methanol, dichloromethane) based on calibrated external standards. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration measuring water via iodine generation and stoichiometric reaction with water in anhydrous methanol-based reagent. |
| Heavy Metals (as Pb) | ICP-MS or ICP-OES | Quantification of trace metals (e.g., Pb, Cd, Hg, As) after acid digestion, using multi-element detection with isotopic resolution (ICP-MS) or elemental emission (ICP-OES). |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride ions using suppressed conductivity detection after aqueous extraction and filtration. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement by observing solid-to-liquid phase change under controlled heating rate (e.g., 1–2 °C/min). |
| Specific Optical Rotation | [α]D (if chiral impurity relevant) | Measurement of plane-polarized light rotation in solution using a digital polarimeter; used to assess chiral purity if asymmetric synthesis is involved. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Determination of inorganic ash content by high-temperature incineration (500–600 °C) followed by weighing of residual residue. |
| Appearance & Color | Visual Inspection / Hazen/APHA Color Scale | Subjective assessment of physical state (crystalline powder) and color intensity against standardized platinum-cobalt color scale solutions. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode to detect acidic/basic impurities. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample using Mie scattering theory to determine volume-based particle size distribution (D10, D50, D90). |
