Manufacturing Quality Control of DL-2-AMINO-4-PENTENOIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 200-220 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC-UV; identification via retention time matching and/or spiked reference standards. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration with iodine-based reagent, where water reacts stoichiometrically with iodine and sulfur dioxide in pyridine/methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after incineration at 500-600 C; weight difference before and after ashing reflects inorganic ash content. |
| Heavy Metals | ICP-OES | Quantifies trace metal contaminants (e.g., Pb, Cd, Hg, As) by plasma excitation and element-specific emission wavelength detection. |
| Chloride | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with suppressed conductivity detection. |
| Sulfate | Ion Chromatography | Separates and quantifies sulfate ions using anion-exchange column with suppressed conductivity detection. |
| Optical Rotation | Polarimetry | Measures specific rotation using sodium D-line light; indicates enantiomeric composition and absence of significant racemization. |
| pH (1% aqueous solution) | Potentiometric pH Measurement | Determines hydrogen ion activity in aqueous solution using calibrated glass electrode and pH meter. |
| Melting Point | Capillary Melting Point Apparatus | Identifies purity and identity by observing temperature range over which solid transitions to liquid under controlled heating. |
| Loss on Drying | Thermogravimetric Analysis | Measures mass loss upon heating at 105 C for 2 h; reflects volatile solvents and moisture content. |
| Specific Optical Rotation | Polarimetry | Confirms stereochemical integrity by measuring observed rotation corrected for concentration and path length at specified wavelength and temperature. |
