Industrial Applications of Z-DAP(FMOC)-OH
| Industry | Application | Process |
|---|---|---|
| Biopharmaceuticals | Bis-orthogonal protecting reagent for L-2,3-diaminopropionic acid residues in solid-phase peptide synthesis | In the Fmoc/tBu strategy, the Fmoc group protects the α-amino group (removed under basic conditions), while the Cbz group protects the side-chain β-amino group (selectively removed via hydrogenolysis or under acidic conditions), enabling stepwise coupling and deprotection |
Manufacturing Quality Control of Z-DAP(FMOC)-OH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Chiral Purity | Chiral HPLC | Separation of enantiomers on a chiral stationary phase with UV detection to confirm L-configuration and detect D-isomer impurity. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., DMF, DCM, methanol) based on retention time and calibration curves. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generation to determine trace water content via stoichiometric reaction with Karl Fischer reagent. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, Ni) after acid digestion, using isotopic detection for high sensitivity and specificity. |
| Residual Chloride | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous extract to assess residual HCl or benzyl chloride derivatives. |
| Related Substances | HPLC-UV | Detection and quantification of structurally related impurities (e.g., mono-Fmoc, deprotected, or oxidation products) using gradient RP-HPLC. |
| Optical Rotation | [alpha]D Measurement | Determination of specific optical rotation at 589 nm using a polarimeter to confirm chiral integrity and batch-to-batch consistency. |
| Melting Point | Capillary Melting Point Apparatus | Thermal analysis by gradual heating to observe solid-to-liquid transition range, indicating crystallinity and purity. |
| Loss on Drying | Gravimetric Heating | Weight loss measurement after drying under controlled temperature and vacuum to assess volatile components and moisture. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) to detect acidic/basic degradation products or residual reagents. |
| Microbial Contamination | Membrane Filtration | Quantitative recovery and enumeration of aerobic microorganisms using sterile filtration followed by culture on TSA agar plates. |
