Manufacturing Quality Control of H-VAL-ALA-OH
| 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 to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and detection of structurally related impurities (e.g., dipeptide isomers, hydrolysis products) via gradient HPLC-UV. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., methanol, acetone, ethyl acetate). |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content in the sample. |
| Optical Rotation | [alpha]D Measurement | Measurement of specific optical rotation using a polarimeter at 20 C and sodium D-line (589 nm) to confirm chiral integrity. |
| Heavy Metals | ICP-MS | Quantitative determination of toxic elements (Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma mass spectrometry. |
| Residue on Ignition | Gravimetric Analysis | Weighing residue remaining after high-temperature ashing (700-800 C) to assess inorganic impurities. |
| pH (1% aqueous solution) | Potentiometric pH Measurement | Direct measurement using calibrated pH electrode in a 1% w/v aqueous solution at 25 C. |
| Chloride Content | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column and suppressed conductivity detection. |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic microorganisms and detection of specified pathogens (e.g., E. coli, S. aureus) per pharmacopeial guidelines. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder particle size distribution using laser scattering principles and Mie theory. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid-to-liquid phase transition occurs under controlled heating rate. |
