Industrial Applications of Bufexamac
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Nonsteroidal anti-inflammatory drug (NSAID) for pain, inflammation, and fever relief | Administered as the active pharmaceutical ingredient (API) in oral dosage forms (e.g., tablets, capsules); absorbed via the gastrointestinal tract to inhibit cyclooxygenase (COX) activity |
| Chemical Research | Organic synthesis intermediate | Used to construct bioactive molecular scaffolds; participates in acylation, esterification, and related reactions |
| Analytical Chemistry | Reference standard or control substance | Employed as a reference material for quantitative and qualitative analysis in high-performance liquid chromatography (HPLC) or mass spectrometry |
Manufacturing Quality Control of Bufexamac
| 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-DAD | Separation and identification of impurities using gradient HPLC with diode-array detection; impurities quantified relative to main peak. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., toluene, ethanol) based on calibrated response factors. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element determination of heavy metals after acid digestion; detection via atomic emission from plasma-excited atoms. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode; endpoint detected by potential change due to AgCl precipitation. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample at 700-800 C after sulfuric acid treatment; residue weighed as inorganic sulfate ash. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent; water reacts stoichiometrically with iodine and sulfur dioxide in methanol/pyridine medium. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature range at which solid transforms to liquid. |
| Appearance | Visual Inspection | Assessment under controlled white light against standard colorless/white reference; detects discoloration, particulates, or phase separation. |
| Acid Value | Acid-Base Titration | Titration with standardized potassium hydroxide solution in ethanol/isopropanol; neutralization of carboxylic acid groups measured by phenolphthalein endpoint. |
| Residue on Ignition | Gravimetric Analysis | Weight loss on ignition at 500-600 C; non-volatile inorganic residue determined after drying and incineration. |
| Bulk Density | Tap Density Measurement | Mass per unit volume after standardized mechanical tapping of powder in a graduated cylinder; measured in g/mL. |
