Manufacturing Quality Control of Z-LEU-ONP
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to certified reference standard. |
| Enantiomeric Purity | Chiral HPLC | Separates (R)- and (S)-enantiomers on a chiral stationary phase; enantiomeric excess calculated from peak area ratio. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., methanol, ethyl acetate, toluene) using gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration using iodine-based reagent in anhydrous methanol medium. |
| Heavy Metals | ICP-OES | Measures total elemental impurities (Pb, Cd, Hg, As, etc.) after acid digestion using inductively coupled plasma optical emission spectroscopy. |
| Residual Chloride | Ion Chromatography | Quantifies chloride ion content via suppressed conductivity detection after aqueous extraction. |
| Residual Benzyl Alcohol | GC-FID | Detects benzyl alcohol as a potential degradation product or residual synthesis intermediate using gas chromatography. |
| Acid Value | Acid-Base Titration | Determines free carboxylic acid content by titration with standardized NaOH solution using phenolphthalein indicator. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or foreign matter against established reference standards. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range over which solid transitions to liquid, indicating purity and identity via comparison to literature value. |
| Loss on Drying | Gravimetric Analysis | Determines volatile content by measuring mass loss after drying under controlled temperature and vacuum conditions. |
| Microbial Limits | Membrane Filtration | Evaluates aerobic microbial count and absence of specified pathogens using culture-based membrane filtration and incubation. |
