Manufacturing Quality Control of METHYL 3,5-DIHYDROXYBENZOATE
| 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 280 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 | Detection and quantification of volatile organic solvents (e.g., methanol, acetone) by gas chromatography with flame ionization detection. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content via iodine-sulfur dioxide reaction in anhydrous methanol-based reagent. |
| Heavy Metals | ICP-OES | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma optical emission spectrometry. |
| Chloride Content | Ion Chromatography | Separation and quantification of chloride ions using suppressed conductivity detection after aqueous extraction. |
| Sulfated Ash | Gravimetric Analysis | Residue mass after high-temperature incineration in presence of sulfuric acid, expressed as percentage of sample weight. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change using calibrated capillary tube method per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of crystalline solid 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 at specified concentration and wavelength. |
| pH of Aqueous Suspension | pH Meter | Measurement of hydrogen ion activity in a saturated aqueous suspension prepared per defined protocol. |
| Particle Size Distribution | Laser Diffraction | Analysis of particle size distribution based on angular scattering pattern of laser beam passing through dispersed sample. |
