Manufacturing Quality Control of H-DL-Pro-NH2
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Prolinamide Content) | HPLC-UV | Quantification based on peak area comparison against reference standard using reversed-phase chromatography and UV detection at 210 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities by reversed-phase HPLC with UV detection, relative to main peak area. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection for volatile organic solvents (e.g., methanol, acetone, ethyl acetate). |
| Water Content | Karl Fischer Titration | Volumetric titration using iodine, sulfur dioxide, and base in methanol-based reagent; measures total water via stoichiometric reaction. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, based on mass-to-charge ratio detection. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride anions using suppressed conductivity detection after eluent gradient. |
| Sulfate Impurity | Ion Chromatography | Separation and quantification of sulfate anions using suppressed conductivity detection under optimized eluent conditions. |
| Residue on Ignition | Gravimetric Analysis | Mass measurement of inorganic residue after high-temperature ashing at 600-700 C in a muffle furnace. |
| pH of Aqueous Solution | Potentiometric Measurement | Determination using calibrated pH electrode in a 1% w/v aqueous suspension or solution. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light through a standardized solution to confirm chiral purity and identity. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to determine volume-based particle size distribution in dispersed suspension. |
| Microbial Contamination | Membrane Filtration | Quantitative enumeration of aerobic microorganisms using filtration, membrane transfer to culture media, and colony counting after incubation. |
