Manufacturing Quality Control of H-LEU-GLY-OH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison with reference standard using reversed-phase chromatography and UV detection at 200-220 nm. |
| Related Substances | HPLC-UV | Separation and detection of structurally related impurities (e.g., dipeptide isomers, hydrolysis products) using gradient HPLC with UV detection. |
| Loss on Drying | Gravimetric (105 C oven drying) | Mass loss measured after drying sample at 105 C to constant weight, reflecting volatile content including residual solvents and water. |
| Residue on Ignition | Gravimetric (Sulfated Ash) | Weight of inorganic residue remaining after high-temperature incineration following sulfuric acid treatment. |
| Heavy Metals (as Pb) | AAS or ICP-OES | Quantification of total heavy metals by atomic absorption spectroscopy or inductively coupled plasma optical emission spectrometry after acid digestion. |
| Chloride Content | Argentometric Titration (Mohr method) | Titration with standardized silver nitrate solution using potassium chromate indicator; endpoint signaled by brick-red Ag2CrO4 precipitate. |
| Sulfate Content | Barium Sulfate Gravimetric Method | Precipitation of sulfate as BaSO4 under controlled acidity and temperature, followed by filtration, drying, and weighing. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral L-亮氨酰甘氨酸 in solution at specified concentration and wavelength (e.g., sodium D line). |
| pH of Solution (1% w/v) | Potentiometric pH Measurement | Determination of hydrogen ion activity in aqueous solution using calibrated glass electrode pH meter. |
| Water Content (Karl Fischer) | Coulometric or Volumetric Karl Fischer Titration | Electrochemical or volumetric titration with iodine-based reagent where water reacts stoichiometrically to determine trace moisture. |
| Microbial Limits | Membrane Filtration and Plate Count | Enumeration of aerobic mesophilic bacteria and yeasts/molds via filtration, membrane transfer to appropriate agar media, and colony counting after incubation. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity pattern to calculate volume-based particle size distribution in dispersed solid sample. |
