Industrial Applications of Z-LYS(BOC)-ONP
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Chiral intermediates for synthesizing lysine-containing protease inhibitors (e.g., anti-HIV drugs) | Amino group protection and coupling steps in solid-phase peptide synthesis (SPPS), enabling sequence elongation via selective removal of Boc and Cbz protecting groups |
Manufacturing Quality Control of Z-LYS(BOC)-ONP
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Chiral Purity | Chiral HPLC | Separation of (R)- and (S)-enantiomers on a chiral stationary phase with UV detection; enantiomeric excess calculated from peak areas. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify common solvents (e.g., methanol, ethyl acetate, toluene) based on calibrated response factors. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to react stoichiometrically with water; endpoint detected potentiometrically. |
| Heavy Metals | ICP-MS | Quantitative determination of trace metals (e.g., Pb, Cd, Ni, Fe) after acid digestion, using mass spectrometric detection of elemental isotopes. |
| Residual Chlorides | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column and suppressed conductivity detection. |
| Residual Benzyl Alcohol | GC-FID | Direct injection GC-FID analysis targeting benzyl alcohol as a process-related impurity, calibrated with external standards. |
| Residual tert-Butyl Alcohol | GC-FID | Headspace or direct injection GC-FID for quantification of residual t-butanol from Boc deprotection steps. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of solid sample against established visual standards under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which the solid transitions to liquid, using calibrated digital melting point instrument. |
| Loss on Drying | Gravimetric Analysis | Weight loss measured after drying under specified vacuum and temperature conditions; reflects volatile content including residual solvents and moisture. |
| Related Substances | HPLC-UV | Detection and quantification of structurally related impurities (e.g., hydrolysis products, di-Boc analogs, des-Bn derivatives) using gradient HPLC with UV detection. |
