Manufacturing Quality Control of METHYL 1-HYDROXY-2-NAPHTHOATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-DAD | Separation and identification of impurities by HPLC coupled with diode array detection, using gradient elution and spectral comparison. |
| Residual Solvents | GC-FID | Determination of volatile organic solvents by gas chromatography with flame ionization detection using headspace sampling. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification of heavy metals after acid digestion, based on atomic emission intensities at characteristic wavelengths. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate solution using a silver indicator electrode; endpoint detected by potential change. |
| Sulfate Content | Gravimetric Analysis | Precipitation as barium sulfate followed by filtration, drying, and weighing of the precipitate. |
| Water Content | Karl Fischer Titration | Volumetric titration using iodine, sulfur dioxide, and pyridine in methanol; water reacts stoichiometrically to consume iodine. |
| pH of Aqueous Solution | pH Meter Measurement | Electrochemical measurement of hydrogen ion activity in a 1% w/v aqueous suspension using calibrated glass electrode. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition temperature using controlled heating and visual observation. |
| Loss on Drying | Gravimetric Heating | Mass loss measured after drying at 105 C for 2 hours under atmospheric pressure. |
| Iron Content | AAS | Atomic absorption spectroscopy after sample digestion; quantification based on absorbance at 248.3 nm. |
| Residue on Ignition | Gravimetric Ashing | Mass of non-volatile inorganic residue after incineration at 600 C for 30 minutes. |
