Manufacturing Quality Control of 4-HYDROXY-3-METHYLBENZOIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at ~280 nm, comparing peak area against a certified reference standard. |
| Loss on Drying (LOD) | Gravimetric Thermogravimetry | Measurement of mass loss after drying at 105 °C under vacuum or nitrogen, reflecting volatile impurities and residual solvents. |
| Residual Solvents (e.g., methanol, ethyl acetate) | GC-FID | Separation and quantification of low-boiling organic solvents by gas chromatography with flame ionization detection using internal standard calibration. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element trace metal quantification via inductively coupled plasma mass spectrometry after acid digestion and matrix-matched calibration. |
| Chloride Impurity | Ion Chromatography (IC) | Anion exchange separation followed by suppressed conductivity detection to quantify chloride ions from potential synthesis residues. |
| Related Substances (Impurity Profile) | HPLC-DAD | Detection and semi-quantification of structurally related impurities (e.g., 3-methylsalicylic acid, unreacted precursors) using diode array detection and relative response factors. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement based on optical observation of solid-to-liquid phase change, indicating crystallinity and purity. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration quantifying water via iodine generation and stoichiometric reaction with sample water in anhydrous medium. |
| pH of Aqueous Suspension (1% w/v) | pH Meter | Measurement of hydrogen ion activity in a saturated aqueous suspension, reflecting acidic character and potential degradation products. |
| Appearance (Color & Clarity) | Visual Inspection against Standard Solutions | Comparison of dissolved sample solution (e.g., in methanol/water) to established color standards (e.g., APHA/Hazen) and visual assessment for particulates or haze. |
