Manufacturing Quality Control of 4-Methoxysalicylic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration with NaOH | Quantifies 4-methoxysalicylic acid by neutralizing its carboxylic acid group using standardized sodium hydroxide solution. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric reaction between water and iodine in a pyridine/methanol electrolyte system. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by ignition at 700-800 C and weighing the residual non-volatile material. |
| Heavy Metals | ICP-OES | Quantifies trace metal impurities (e.g., Pb, Cd, Hg) by plasma excitation and elemental emission spectroscopy. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after sulfation and high-temperature ignition, indicating sulfate-forming impurities. |
| Related Substances | HPLC with UV Detection | Separates and quantifies structurally related impurities using reversed-phase chromatography and UV absorbance at 254 nm. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity. |
| Loss on Drying | Thermogravimetric Analysis (TGA) | Measures mass loss upon heating under controlled conditions to assess volatile content including solvents and water. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Evaluates acidity/basicity of a saturated aqueous suspension using calibrated pH electrode. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Detects and quantifies residual solvents (e.g., methanol, acetone) using flame ionization detection. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light to confirm chiral integrity and absence of racemization (if applicable). |
