Industrial Applications of FMOC-D-ASP-OTBU
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Intermediate for peptide synthesis | Used as a protected amino acid in solid-phase or solution-phase peptide synthesis to incorporate D-aspartic acid residues |
| Biotechnology | Chiral building block in drug development | Applied in stereoselective reactions leveraging its chiral structure to synthesize peptides with defined configuration |
| Fine chemicals | Organic synthesis building block | Deprotected under basic conditions and subsequently employed in amide bond formation for stepwise construction of complex molecules |
Manufacturing Quality Control of FMOC-D-ASP-OTBU
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 260-280 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., deprotected forms, diastereomers, hydrolysis products) using gradient HPLC with UV detection. |
| Residual Solvents | GC-FID | Measures trace organic solvents (e.g., DMF, THF, DCM, methanol) by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine-based redox reaction in anhydrous methanol/pyridine medium. |
| Optical Purity (Enantiomeric Excess) | Chiral HPLC-UV | Separates D- and L-enantiomers on a chiral stationary phase and calculates enantiomeric excess from peak area ratio. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pb, Cd, Hg, As, Ni) after acid digestion using inductively coupled plasma mass spectrometry. |
| Residual Palladium | ICP-MS | Specific quantification of palladium residues (from coupling catalysts) after microwave-assisted digestion and ICP-MS analysis. |
| Chloride Content | Ion Chromatography | Measures chloride ion concentration using suppressed conductivity detection after aqueous extraction. |
| Sulfated Ash | Gravimetric Analysis | Determines inorganic residue after controlled combustion at 500-600 C followed by precise weighing of the ash. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of solid particles in suspension using Mie scattering theory and laser diffraction optics. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary apparatus with controlled heating rate. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Measures hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using calibrated glass electrode and pH meter. |
