Manufacturing Quality Control of 4-ETHOXYCINNAMIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 280-320 nm, comparing peak area against a certified reference standard. |
| Appearance | Visual Inspection | Assessment of physical state and color by observation under controlled white light against established visual standards. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, using calibrated capillary apparatus per USP <741>. |
| Loss on Drying | Gravimetric (105 C, 2 h) | Measurement of mass loss after drying under specified temperature and time, indicating volatile content including residual solvents and moisture. |
| Residual Solvents | GC-FID | Separation and quantification of common organic solvents (e.g., ethanol, ethyl acetate) using gas chromatography with flame ionization detection. |
| Heavy Metals | ICP-OES | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, based on atomic emission intensities. |
| Chloride Impurity | Ion Chromatography | Separation and detection of chloride ions using suppressed conductivity detection after anion exchange separation. |
| Sulfated Ash | Gravimetric (500-600 C) | Determination of inorganic residue mass after charring and sulfuric acid treatment followed by high-temperature ignition. |
| Related Substances | HPLC-DAD | Detection and quantification of structurally related impurities (e.g., 4-hydroxy-, 4-methoxy-, or dihydro derivatives) using diode array detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration with iodine-based reagent to determine trace water content via stoichiometric reaction. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined saturated aqueous suspension using calibrated pH electrode per EP 2.2.3. |
| Specific Optical Rotation | Polarimetry | Determination of rotation angle of plane-polarized light through a solution, indicating chiral purity and absence of racemization. |
