Manufacturing Quality Control of Boc-Asp-OH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 210 nm. |
| Chiral Purity | Chiral HPLC | Separation of L- and D-enantiomers on a chiral stationary phase, with quantification via UV detection to determine enantiomeric excess. |
| Loss on Drying | Gravimetric (Thermogravimetry) | Measurement of mass loss after drying under controlled temperature and vacuum or nitrogen purge to determine volatile content including residual solvents and water. |
| Residual Solvents | GC-FID | Identification and quantification of common organic solvents (e.g., DMF, THF, ethyl acetate) using gas chromatography with flame ionization detection. |
| Heavy Metals | ICP-MS | Multi-element detection and quantification of toxic metals (e.g., Pb, Cd, Hg, As) at trace levels using inductively coupled plasma mass spectrometry. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with suppressed conductivity detection. |
| Sulfate Impurity | Ion Chromatography | Separation and quantification of sulfate ions using anion-exchange column with suppressed conductivity detection. |
| Related Substances | HPLC-UV | Detection and quantification of structurally related impurities (e.g., Boc-Asp-OH degradants, di-Boc-Asp, free aspartic acid) by gradient reversed-phase HPLC. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration with iodine-based reagent to specifically determine water content based on stoichiometric reaction. |
| Specific Optical Rotation | Polarimetry | Measurement of the angle of rotation of plane-polarized light to confirm chiral identity and assess optical purity. |
| pH (1% w/v aqueous solution) | Potentiometric pH Measurement | Determination of hydrogen ion activity in a standardized aqueous solution using calibrated glass electrode and pH meter. |
| Residue on Ignition | Gravimetric (Sulfated Ash) | Measurement of non-volatile inorganic residue after high-temperature incineration in presence of sulfuric acid, indicating inorganic impurities. |
