| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Synthesis of cyclopropane moieties in certain drug molecules | Catalytic hydrogenation or other chemical reactions convert unsaturated compounds into 1-fluorocyclopropanecarboxylic acid, which is subsequently used in the synthesis of target pharmaceuticals |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID or MS detection | Quantifies main component by separation and detection based on volatility and retention time relative to certified reference standard. |
| Related Substances (Impurities) | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies organic impurities via mass spectral fragmentation patterns and retention time matching. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) with FID | Separates and quantifies volatile solvents (e.g., methanol, dichloromethane) using equilibrium vapor phase analysis. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Determines trace water via electrochemical iodine generation and stoichiometric reaction with water in anhydrous medium. |
| Acid Value | Acid-Base Potentiometric Titration | Measures total acidic functionality by titration with standardized NaOH solution; endpoint detected by pH inflection. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantifies elemental impurities (e.g., Pb, Cd, Hg, As) after acid digestion using element-specific atomic emission lines. |
| Chloride Content | Ion Chromatography (IC) with Conductivity Detection | Separates and quantifies chloride ions via ion-exchange chromatography and suppressed conductivity measurement. |
| Optical Rotation | [α]D at 20 °C | Measures specific rotation using sodium D-line light to assess enantiomeric purity if chiral synthesis route is employed. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Determines inorganic ash content by high-temperature combustion and weighing of residual non-volatile residue. |
| pH of Aqueous Solution (1% w/v) | Potentiometric pH Measurement | Evaluates acidity/basicity of aqueous dispersion using calibrated pH electrode in standardized suspension. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using controlled heating and visual observation of phase change. |
| Appearance | Visual Inspection (in specified container under controlled lighting) | Assesses physical state, color, and clarity against established reference standards under standardized viewing conditions. |
