Manufacturing Quality Control of 4-HYDROXYISOLEUCINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 200-210 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of structurally similar impurities using gradient HPLC-UV; identification based on retention time matching and threshold limits per ICH Q3B. |
| Optical Rotation | [alpha]D | Measurement of specific optical rotation using a polarimeter at 20-25 C and sodium D-line (589 nm) to confirm chiral integrity and enantiomeric purity. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration with iodine-based reagent to determine trace water content based on stoichiometric reaction with water. |
| Residue on Ignition | Gravimetric Analysis | Heating sample at 700-800 C to constant weight; residue mass expressed as percentage of original sample to assess inorganic ash content. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion, using plasma emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with conductivity detection; calibrated against NaCl standards. |
| Sulfate Impurity | Turbidimetry | Reaction with barium chloride under acidic conditions to form BaSO4 precipitate; quantification via light scattering measurement. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Direct measurement using calibrated glass electrode in a 1% w/v aqueous solution at 25 C. |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic mesophilic bacteria, yeasts, and molds by filtration, membrane transfer to selective media, and colony counting after incubation. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion using laser scattering to determine volume-based particle size distribution (D10, D50, D90). |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, using calibrated capillary method per USP <741>. |
