Manufacturing Quality Control of L-CYCLOSERINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at 210 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and detection of impurities by gradient HPLC-UV; identification and quantification based on relative retention times and response factors. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to react stoichiometrically with water in the sample. |
| Residue on Ignition | Gravimetric Analysis | Heating the sample at 700-800 C to constant weight and measuring non-volatile inorganic residue as percentage of original mass. |
| Heavy Metals | ICP-OES | Multi-element detection after acid digestion, measuring emission intensities of metal atoms excited in plasma. |
| Chloride | Potentiometric Titration | Titration with silver nitrate using a silver/silver chloride electrode to detect endpoint via potential change. |
| Sulfate | Barium Sulfate Gravimetry | Precipitation as BaSO4 in acidic medium followed by filtration, drying, and weighing of the precipitate. |
| Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution of the compound at specified concentration and wavelength. |
| pH of Solution | pH Meter | Direct potentiometric measurement of hydrogen ion activity in a 1% aqueous solution using calibrated glass electrode. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns to determine size distribution of dry or suspended particles. |
| Microbial Limits | Membrane Filtration | Filtration of sample solution, rinsing, and incubation on selective agar media for enumeration of aerobic microorganisms. |
| Residual Solvents | GC-FID | Separation by gas chromatography and quantification using flame ionization detection, compared to internal standard calibration. |
