Industrial Applications of ALPHA-BOC-GAMMA-Z-(DL)-DIAMINOBUTYRIC ACID
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Bis-protecting reagent for L-2,4-diaminobutyric acid (Dab) residues in peptide synthesis, enabling selective protection of the side-chain amino group and the backbone amino group | Used as a controlled coupling precursor in solid-phase peptide synthesis (SPPS) or solution-phase peptide synthesis; the α-amino group is protected with tert-butoxycarbonyl (Boc), the δ-amino group on the side chain is protected with benzyloxycarbonyl (Cbz), and the compound is supplied as a dicyclohexylamine salt to enhance crystallinity and handling stability |
| Organic Synthesis | Building block for drug intermediates containing diamino structural motifs (e.g., antimicrobial peptide mimetics, targeted conjugation molecules) | Orthogonal deprotection: Boc group is removed under acidic conditions (e.g., TFA) to enable backbone elongation, followed by hydrogenolysis to remove the Cbz group |
Manufacturing Quality Control of ALPHA-BOC-GAMMA-Z-(DL)-DIAMINOBUTYRIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at 210 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and detection of impurities by gradient HPLC-UV; identification and quantification relative to main peak. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., methanol, ethyl acetate, toluene) based on retention time and calibration curves. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content via stoichiometric reaction. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification after acid digestion using inductively coupled plasma mass spectrometry with isotope dilution or external calibration. |
| Residual Palladium | ICP-OES | Quantification of Pd after microwave-assisted acid digestion using inductively coupled plasma optical emission spectroscopy. |
| Chloride Content | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous solution after sample dissolution and filtration. |
| Optical Rotation | [alpha]D | Measurement of specific rotation using sodium D-line light source in a polarimeter to confirm chiral integrity and enantiomeric purity. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, indicating crystallinity and absence of significant impurities. |
| Residue on Ignition | Gravimetric Analysis | Weighing residue remaining after high-temperature ashing to assess inorganic impurities and catalyst residues. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) to verify acid-base character consistent with salt form. |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic microorganisms and detection of specified pathogens (e.g., E. coli, S. aureus) per pharmacopeial methods. |
