Manufacturing Quality Control of BOC-D-Leucine monohydrate
| 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 D- and L-enantiomers on a chiral stationary phase; enantiomeric excess calculated from peak area ratios. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., ethyl acetate, toluene). |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma mass spectrometry. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride anions in aqueous solution after sample dissolution and filtration. |
| Sulfated Ash | Gravimetric Analysis | Incineration at 600-700 C followed by weighing of non-volatile inorganic residue after sulfuric acid treatment. |
| Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution to confirm chiral integrity and concentration. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns to determine volume-based particle size distribution in dry or slurry form. |
| Microbial Contamination | Membrane Filtration | Filtration of dissolved sample followed by incubation on nutrient agar plates to enumerate aerobic microorganisms. |
| Related Substances | HPLC-DAD | Detection and relative quantification of structurally related impurities using diode array detection across multiple wavelengths. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination of hydrogen ion activity in a saturated aqueous suspension using a calibrated glass electrode and reference electrode. |
