Manufacturing Quality Control of Methyl L-leucinate hydrochloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies L-leucine methyl ester hydrochloride by reversed-phase HPLC with UV detection at 200-220 nm, using a calibrated standard. |
| Water Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration with iodine-based reagent, based on stoichiometric reaction with water. |
| Residual Solvents | GC-FID | Identifies and quantifies common organic solvents (e.g., methanol, ethyl acetate) using gas chromatography with flame ionization detection. |
| Heavy Metals | ICP-OES | Measures total heavy metal content (Pb, Cd, Hg, As, etc.) after acid digestion by optical emission spectroscopy. |
| Chloride Content | Potentiometric Titration | Determines chloride ions using silver nitrate titrant and silver/silver chloride indicator electrode. |
| Optical Rotation | [alpha]D Measurement | Measures specific optical rotation at 20 °C using sodium D-line (589 nm) to confirm chiral integrity and enantiomeric purity. |
| pH (1% aqueous solution) | pH Meter | Determines acidity of a 1% w/v aqueous solution using calibrated pH electrode in accordance with USP/EP general chapter. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., L-leucine, methyl ester hydrolysis products) using gradient HPLC with UV detection. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic residue after high-temperature ashing (700-800 °C) and weighing of the residual ash. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, confirming identity and purity based on sharpness and agreement with reference value. |
| Microbial Limits | Membrane Filtration | Quantifies aerobic mesophilic microorganisms and detects specified pathogens (e.g., E. coli, S. aureus) per pharmacopoeial methods. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution in dry powder form using light scattering principles and Mie theory. |
