Manufacturing Quality Control of 5-PHENYLPENTA-2,4-DIENOIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 210-230 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and detection of structurally similar impurities using gradient HPLC-UV; identification and quantification against reference standards or threshold limits. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify volatile organic solvents (e.g., methanol, ethyl acetate) based on calibrated response factors. |
| Water Content | Karl Fischer Titration | Electrochemical titration with iodine-based reagent to determine trace water content via stoichiometric reaction with iodine and sulfur dioxide. |
| Heavy Metals | ICP-OES | Multi-element determination after acid digestion by measuring atomic emission intensities of metals (e.g., Pb, Cd, Hg, As) in plasma. |
| Chloride Content | Ion Chromatography | Separation and quantification of chloride anions using suppressed conductivity detection after aqueous extraction. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample at 700-800 C followed by sulfuric acid treatment and final weighing of non-volatile residue. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white light and against established reference standards. |
| Acid Value | Acid-Base Titration | Neutralization of carboxylic acid groups with standardized potassium hydroxide solution using phenolphthalein indicator. |
| Loss on Drying | Thermogravimetric Analysis | Weight loss measured after drying at 105 C for 2 hours under forced-air conditions to determine volatile content. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light through a solution using sodium D-line (589 nm) to assess chiral purity and identity. |
