Manufacturing Quality Control of TRANS-2,4-DICHLOROCINNAMIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Identity | FTIR Spectroscopy | Confirmation by matching characteristic functional group absorption bands (e.g., C=O, C=C, C-Cl) to reference spectrum. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, compared to literature value (138-140 C). |
| Loss on Drying | Gravimetric (Thermogravimetric) | Measurement of mass loss after drying at 105 C for 2 hours under controlled conditions. |
| Residual Solvents | GC-FID | Quantification of volatile organic solvents (e.g., methanol, ethyl acetate) using gas chromatography with flame ionization detection. |
| Heavy Metals (as Pb) | AAS (Air-Acetylene) | Atomic absorption spectroscopy after acid digestion and chelation, measuring absorbance at characteristic wavelength for lead. |
| Chloride Impurities | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode; endpoint detected by potential change due to AgCl precipitation. |
| Related Substances | HPLC-DAD | Separation and detection of structurally related impurities (e.g., cis-isomer, mono-chloro analogs) using diode array detection. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemical titration quantifying water via iodine generation proportional to water content in the sample. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to determine volume-based particle size distribution in dry dispersion mode. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution, confirming chiral purity and absence of racemization. |
| Residue on Ignition | Gravimetric (Sulfated Ash) | Mass of non-volatile residue remaining after high-temperature ignition (700-750 C) following sulfuric acid treatment. |
