Industrial Applications of Boc-D-Phe-Phe
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Chiral intermediate in peptide-based drug synthesis for constructing D-phenylalanine residues | Used as a protected amino acid monomer in solid-phase peptide synthesis (SPPS); participates in amide bond coupling reactions following BOC deprotection |
| Biopharmaceuticals | Design and preparation of novel protease inhibitors and targeted anticancer peptides | Applied in liquid-phase peptide fragment condensation, leveraging its high optical purity and stable tert-butoxycarbonyl (BOC) protecting group for selective coupling |
Manufacturing Quality Control of Boc-D-Phe-Phe
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 210–220 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of structurally related impurities (e.g., BOC-D-Phe-OH, D-Phe-Phe, hydrolysis/degradation products) using gradient HPLC-UV. |
| Residual Solvents | GC-FID | Identification and quantification of residual solvents (e.g., DMF, dichloromethane, methanol) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on the stoichiometric reaction of iodine with water in a pyridine/methanol solvent system. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma mass spectrometry for sub-ppb sensitivity. |
| Optical Rotation | [α]D | Measurement of specific optical rotation using a polarimeter at 20 °C with sodium D-line (589 nm) to confirm chiral integrity and enantiomeric purity. |
| Residue on Ignition | Gravimetric Analysis | Determination of inorganic ash content by ignition at 700–800 °C followed by precise weighing of residual inorganic matter. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample via light scattering to determine D10, D50, D90 values per USP <429>. |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic microorganisms (TAMC) and absence of specified pathogens (e.g., E. coli, S. aureus) per USP <61> and <62>. |
