Manufacturing Quality Control of L-Prolinamide hydrochloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at 200-220 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and detection of structurally similar impurities using gradient HPLC-UV; identification and quantification relative to main peak. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents based on retention time and peak area. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content via stoichiometric reaction. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, As, Hg, and others by measuring atomic emission intensities after acid digestion and plasma excitation. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using silver electrode to detect endpoint based on potential change from AgCl precipitation. |
| pH (1% w/v solution) | pH Meter Measurement | Direct measurement of aqueous solution pH using calibrated glass electrode and temperature-compensated pH meter. |
| Specific Optical Rotation | [alpha]D Measurement | Determination of chiral purity by measuring rotation of plane-polarized light at 589 nm using sodium D-line source and standardized cell path length. |
| Loss on Drying | Gravimetric Analysis | Weight loss measured after drying sample at specified temperature (e.g., 105 C) under vacuum or air until constant mass is achieved. |
| Residue on Ignition | Gravimetric Analysis | Mass of inorganic residue remaining after high-temperature ashing (e.g., 600-700 C), indicating non-volatile inorganic impurities. |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic bacteria, yeasts, molds, and absence of specified pathogens using selective culture media and filtration followed by incubation. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or dispersed sample using laser scattering pattern to calculate volume-based particle size distribution. |
