Manufacturing Quality Control of 4-ETHYL-1-NAPHTHOIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorbance at specific wavelength using reverse-phase C18 column and calibrated standard. |
| Related Substances | HPLC-DAD | Detects and quantifies structurally similar impurities via diode array detection and peak area comparison. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents using flame ionization detection with capillary column. |
| Moisture Content | Karl Fischer Titration | Measures water content via stoichiometric reaction between iodine, sulfur dioxide, and water in pyridine/methanol medium. |
| Heavy Metals | ICP-OES | Determines total heavy metal content (e.g., Pb, Cd, Hg, As) by atomic emission spectroscopy after acid digestion. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after combustion with sulfuric acid treatment and high-temperature ignition. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light against standard reference. |
| Acid Value | Acid-Base Titration | Quantifies free carboxylic acid groups by titration with standardized NaOH solution using phenolphthalein indicator. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of solid particles in suspension by analyzing angular scattering pattern of laser beam. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic residue after high-temperature ignition without sulfuric acid pretreatment. |
