Manufacturing Quality Control of L-Citrulline-Dl-Malate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (L-Citrulline DL-Malate) | Acid-Base Titration | Quantifies total acidic protons from malic acid and citrulline carboxyl groups using standardized NaOH solution. |
| Loss on Drying | Gravimetric Analysis | Measures weight loss after drying at 105 C under vacuum to determine volatile content including water and residual solvents. |
| Water Content | Karl Fischer Titration | Determines water by volumetric or coulometric reaction between water and iodine in pyridine/methanol medium. |
| Residual Solvents (e.g., Ethanol, Acetone) | Gas Chromatography (GC-FID) | Separates and quantifies volatile organic solvents based on retention time and flame ionization detection. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Simultaneously detects trace metals after acid digestion by measuring element-specific atomic emission intensities. |
| Chloride Impurity | Potentiometric Titration | Quantifies chloride ions using silver nitrate titrant with silver indicator electrode and reference electrode. |
| Sulfate Impurity | Gravimetric Analysis | Precipitates sulfate as barium sulfate under controlled pH and temperature; mass of precipitate correlates to sulfate content. |
| Related Substances | HPLC-UV | Separates and quantifies structurally related impurities (e.g., L-citrulline, DL-malic acid, degradation products) using reversed-phase column and UV detection. |
| Optical Rotation | Polarimetry | Measures specific rotation of chiral compound in solution to confirm identity and enantiomeric purity of L-citrulline moiety. |
| pH (1% aqueous solution) | pH Potentiometry | Determines hydrogen ion activity using calibrated glass electrode in a defined aqueous suspension. |
| Microbial Limits | Membrane Filtration | Quantifies aerobic bacteria, yeasts, and molds by filtration, membrane transfer to selective agar, and colony enumeration. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution by analyzing angular variation in intensity of laser light scattered by dispersed particles. |
