Industrial Applications of Ac-D-Gln-OH
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Used as a protected amino acid monomer in peptide synthesis to construct peptide chains containing glutamine residues | Participates in coupling reactions as an N-acetylated, side-chain unprotected D-glutamine derivative in solid-phase peptide synthesis (SPPS) or solution-phase peptide synthesis |
| Biochemical Research | Used to investigate the role of D-amino acids in peptide structure and function, including enzyme stability and receptor binding properties | Introduced into target peptide sequences as a reference standard or building block via Fmoc/t-Boc strategies |
| Medicinal Chemistry | Applied in developing peptide-based drug candidates with improved metabolic stability by leveraging the D-configuration for enhanced resistance to enzymatic degradation | Employed as a non-natural amino acid building block for structural modification during combinatorial library construction or lead compound optimization |
Manufacturing Quality Control of Ac-D-Gln-OH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 210 nm, comparing peak area against a certified reference standard. |
| Chiral Purity | Chiral HPLC | Separation of D- and L-enantiomers on a chiral stationary phase, with UV detection to calculate enantiomeric excess. |
| Water Content | Karl Fischer Titration | Electrochemical titration with iodine-based reagent to quantify trace water based on stoichiometric reaction. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to identify and quantify volatile organic solvents. |
| Heavy Metals | ICP-MS | Multi-element detection of toxic metals (e.g., Pb, Cd, Hg) by inductively coupled plasma mass spectrometry after acid digestion. |
| Related Substances | HPLC-UV | Detection and quantification of structurally similar impurities using gradient HPLC with UV detection. |
| Optical Rotation | [alpha]D Measurement | Measurement of specific rotation using a polarimeter at specified temperature and wavelength (e.g., 589 nm, 20 C). |
| pH (1% w/v aqueous solution) | Potentiometric pH Measurement | Determination of hydrogen ion activity using calibrated glass electrode in aqueous solution. |
| Loss on Drying | Gravimetric Thermogravimetry | Weight loss measured after drying under controlled temperature and vacuum to assess volatile content. |
