Industrial Applications of ETHYL 5-METHYLISOXAZOLE-3-CARBOXYLATE
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Industry | Intermediate for sulfonamide drugs (e.g., sulfisoxazole) and antibacterial synergists | Serves as a starting material or key intermediate; the isoxazole ring is introduced via amidolysis, condensation, and related reactions |
| Pharmaceutical Industry | Synthetic raw material for nonsteroidal anti-inflammatory drugs (e.g., isoxicam) | Hydrolyzed to the corresponding carboxylic acid, followed by amidation or condensation with other heterocycles to construct the drug molecule scaffold |
| Agrochemical Industry | Intermediate for fungicides and insecticides | The isoxazole ring undergoes further chemical modification—such as alkylation or acylation—to synthesize active ingredients |
| Organic Synthesis | General building block for isoxazole derivatives | Reduced at the ester group to yield alcohol derivatives, or reacted with hydrazine to produce acyl hydrazide compounds, enabling construction of complex molecules |
| Physicochemical Research | Mechanistic studies of organic reactions | Used as a model compound to investigate ring-opening and rearrangement reactions of the isoxazole system under acidic or basic conditions |
Manufacturing Quality Control of ETHYL 5-METHYLISOXAZOLE-3-CARBOXYLATE
| 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 to a certified reference standard. |
| Related Substances | HPLC-DAD | Separation and detection of impurities using HPLC coupled with diode-array detection, with identification and quantification against qualified impurity standards. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection for quantitative analysis of volatile organic solvents based on retention time and peak area. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to react stoichiometrically with water, measuring endpoint potentiometrically or coulometrically. |
| Heavy Metals | ICP-MS | Quantitative multi-element analysis of toxic metals (e.g., Pb, Cd, Hg, As) by inductively coupled plasma mass spectrometry after acid digestion. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions using anion-exchange column with suppressed conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Incineration at 700-800 C followed by sulfuric acid treatment and final weighing of residual inorganic ash. |
| Optical Rotation | [alpha]D Measurement | Determination of specific optical rotation using a polarimeter at 20 C with sodium D-line (589 nm) to confirm chiral integrity. |
| Melting Point | Capillary Melting Point Apparatus | Thermal analysis by observing the temperature range over which solid-to-liquid phase transition occurs under controlled heating. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against established reference standards under controlled lighting conditions. |
| pH of Aqueous Solution | pH Meter | Measurement of hydrogen ion activity in a saturated aqueous suspension using a calibrated glass electrode pH meter. |
| Residue on Ignition | Gravimetric Analysis | Weighing of non-volatile residue remaining after ignition at 600-650 C, indicating inorganic contaminants or catalyst residues. |
