Manufacturing Quality Control of Methyl 3,5-dihydroxybenzoate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC with UV detection; identification based on retention time matching and threshold limits per ICH Q3A/B. |
| Residual Solvents | GC-FID | Detection and quantification of volatile organic solvents (e.g., methanol, ethyl acetate) using gas chromatography with flame ionization detection and internal standard calibration. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content based on stoichiometric reaction with water. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion, using inductively coupled plasma optical emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with conductivity detection and external calibration. |
| Sulfated Ash | Gravimetric Analysis | Determination of inorganic residue after controlled incineration at 600-700 C, followed by precise weighing of the ash. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement by observing the temperature range over which solid-to-liquid phase change occurs under controlled heating. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles against established reference standards under controlled lighting. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral centers in solution, reported as degrees per dm/g. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination of hydrogen ion activity in a saturated aqueous suspension using calibrated glass electrode and pH meter. |
| Particle Size Distribution | Laser Diffraction | Analysis of particle size distribution in dry powder form using Mie scattering theory applied to laser diffraction patterns. |
