Manufacturing Quality Control of D-2-Aminobutyric acid
| Detection Item | Common Testing Method | Method Overview |
|---|---|---|
| Purity Determination | High-Performance Liquid Chromatography (HPLC) | Uses reversed-phase or chiral chromatographic columns combined with UV or evaporative light scattering detectors to quantitatively analyze the main component's purity and separate impurities. |
| Enantiomeric Purity (Optical Purity) | Chiral High-Performance Liquid Chromatography (Chiral HPLC) | Employs chiral stationary phase columns to separate D- and L-enantiomers, calculates enantiomeric excess (ee value), ensuring correct stereochemical configuration. |
| Content Determination | Pre-column Derivatization-HPLC Method | Derivatizes amino acids using reagents such as o-phthalaldehyde (OPA) or dansyl chloride to enhance detection sensitivity before quantitative analysis by HPLC. |
| Moisture Content | Karl Fischer Titration | Determines water content via coulometric or volumetric Karl Fischer titration, ensuring compliance with loss-on-drying or moisture content specifications. |
| Residual Solvents | Gas Chromatography (GC) | Uses headspace or direct injection GC coupled with FID or MS detection to quantify organic solvent residues (e.g., methanol, ethanol). |
| Heavy Metal Content | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | After sample digestion, ICP-MS precisely measures trace levels of harmful heavy metals such as lead, arsenic, cadmium, and mercury. |
| Loss on Drying | Drying Method | Dries samples at a specified temperature (e.g., 105°C) to constant weight, calculating the percentage of mass loss to assess volatile substances and moisture content. |
| pH Value | pH Meter Method | Prepares a solution of defined concentration and measures its acidity/alkalinity using a calibrated pH meter to verify compliance with product specifications. |
| Melting Point Determination | Capillary Melting Point Apparatus Method | Uses a digital melting point apparatus to determine the initial and final melting temperatures, verifying crystalline form and consistency of purity. |
| Specific Rotation | Polarimeter Method | Measures optical rotation of a standard concentration solution at a specified wavelength (typically 589 nm) to confirm optical activity and configurational purity. |
