Manufacturing Quality Control of 4-Hydroxycinnamic acid
| 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 ~310 nm. |
| Related Substances | HPLC-UV | Separation and detection of structurally related impurities (e.g., coumaric acid isomers, dihydrocaffeic acid) using gradient elution and UV monitoring. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., methanol, ethyl acetate) by gas chromatography with flame ionization detection. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma mass spectrometry for ultra-trace sensitivity. |
| Loss on Drying | Gravimetric (Thermogravimetric) | Mass loss measured after drying at 105 C for 2 h; reflects volatile content including residual water and low-boiling solvents. |
| Residue on Ignition | Gravimetric (Sulfated Ash) | Mass of inorganic residue remaining after high-temperature incineration (700–800 C) following sulfuric acid treatment. |
| Chloride Content | Ion Chromatography | Separation and conductivity detection of chloride ions after sample dissolution and filtration; measures inorganic halide impurities. |
| Sulfated Ash | Gravimetric | Mass of non-volatile inorganic residue after ignition at 600–700 C following sulfuric acid addition to convert carbonates to sulfates. |
| pH of Aqueous Solution | Potentiometric Titration | Measurement of hydrogen ion activity in a saturated aqueous suspension using a calibrated pH electrode. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid transitions to liquid, indicating crystallinity and purity. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light caused by chiral centers in solution; confirms enantiomeric identity and absence of racemization. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as a function of angle to derive volume-based particle size distribution in dispersed dry or wet samples. |
