Industrial Applications of FMOC-D-GLN-OH
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Intermediate for peptide drug synthesis, used to construct peptide chains containing glutamine residues | Employed as a protected amino acid monomer in solid-phase peptide synthesis (SPPS); chain elongation proceeds via Fmoc deprotection |
| Biochemistry | Structural modification or labeling in protein and peptide research | Used as a tool molecule for site-specific incorporation of D-glutamine in chiral studies or preparation of stabilized peptide analogs |
| Research Reagents | Building block in organic synthesis or bioconjugation chemistry | Participates in amide bond formation reactions—e.g., conjugation to carrier molecules—via activation of its amino and carboxyl groups |
Manufacturing Quality Control of FMOC-D-GLN-OH
| 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 265 nm. |
| Chiral Purity | Chiral HPLC | Separation of D- and L-enantiomers on a chiral stationary phase with UV detection; D-isomer content calculated relative to total glutamine peak area. |
| Residual Solvents | GC-FID | Identification and quantification of common solvents (e.g., DMF, dichloromethane, methanol) using flame ionization detection after headspace or direct injection. |
| Water Content | Karl Fischer Titration | Coulometric or volumetric titration with iodine-based reagent; water reacts stoichiometrically to determine trace moisture content. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) via inductively coupled plasma mass spectrometry after acid digestion. |
| Residual Chloride | Ion Chromatography | Quantitative determination of chloride anion using suppressed conductivity detection after separation on an anion-exchange column. |
| Related Substances | HPLC-UV | Detection and quantification of structurally related impurities (e.g., FMOC-Gln-OH deprotection products, dipeptide dimers) using gradient reversed-phase HPLC. |
| Loss on Drying | Gravimetric Analysis | Mass loss measured after drying under controlled temperature and vacuum; reflects volatile impurities and residual solvents. |
| Specific Optical Rotation | Polarimetry | Measurement of optical rotation at 20 degrees C using sodium D-line (589 nm); confirms chiral integrity and concentration-dependent rotation. |
| pH of Solution | Potentiometric pH Measurement | Determination of pH in a defined aqueous solution (e.g., 1% w/v in water) using calibrated glass electrode and pH meter. |
| Microbial Contamination | Membrane Filtration + Culture | Enumeration of aerobic microorganisms by filtration, membrane transfer to nutrient agar, and incubation followed by colony counting. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder particle size via scattering pattern measurement of dispersed particles in air using Mie theory-based calculation. |
