| Pharmaceuticals | Synthesis of amino acid derivatives | Applied in the preparation of biologically active non-natural amino acids, modified via esterification or amidation |
| Chemicals | Synthesis of polymeric materials | Employed as a monomer component in polyamides or polyurethanes, participating in condensation polymerization |
| Pesticides | Synthesis of novel insecticide intermediates | Utilized as a building block for nitrogen-containing heterocyclic compounds, involved in cyclization or substitution reactions |
| Research | Biochemical research reagent | Used as a tracer in metabolic pathway studies or as a model compound for enzyme inhibition |
Manufacturing Quality Control of D-2-Aminoadipic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies D-2-Aminoadipic acid content by titration with standardized NaOH using phenolphthalein or potentiometric endpoint detection. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric reaction between water and iodine generated in situ from KF reagent. |
| Specific Optical Rotation | Polarimetry | Measures the angle of rotation of plane-polarized light caused by chiral D-2-aminoadipic acid in solution. |
| Heavy Metals | ICP-OES | Quantifies metal impurities (e.g., Pb, Cd, Fe) by atomization and emission spectroscopy after acid digestion. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue remaining after high-temperature ashing of the sample. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 and determines mass after filtration and drying. |
| Related Substances | HPLC with UV Detection | Separates and quantifies structurally related impurities using reversed-phase chromatography and UV absorbance at 200-220 nm. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity in a defined aqueous suspension or solution using calibrated pH electrode. |
| Melting Point | Capillary Melting Point Determination | Determines temperature range at which solid transitions to liquid using controlled heating and visual observation. |
| Loss on Drying | Thermogravimetric Analysis | Measures weight loss upon heating under controlled conditions to determine volatile content including solvents and moisture. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles against established reference standards under controlled lighting. |
