| Research Reagents | Research and development of peptide sequences | Stepwise coupling process in peptide synthesis |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorption at 268 nm using reverse-phase C18 column and gradient elution with aqueous acetonitrile. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., deletion sequences, diastereomers) via reverse-phase HPLC with UV detection. |
| Chiral Purity | Chiral HPLC | Resolves enantiomeric impurities using chiral stationary phase; confirms L-configuration of phenylalanine residue. |
| Residual Solvents | GC-FID | Quantifies volatile organic solvents (e.g., DMF, DCM, methanol) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures trace water content volumetrically using iodine-based redox titration in anhydrous methanol/pyridine medium. |
| Heavy Metals | ICP-MS | Determines trace metal contaminants (e.g., Pd, Ni, Cu) by inductively coupled plasma mass spectrometry after acid digestion. |
| Residual Palladium | ICP-OES | Quantifies palladium from coupling catalysts using inductively coupled plasma optical emission spectroscopy. |
| Optical Rotation | [alpha]D Measurement | Measures specific rotation at 589 nm to confirm chiral integrity and batch-to-batch consistency. |
| pH (1% w/v solution) | Potentiometric Titration | Determines acidity/basicity of aqueous solution using calibrated pH electrode. |
| Loss on Drying | Gravimetric Analysis | Measures volatile content by weight loss after drying under controlled temperature and vacuum. |
| Particle Size Distribution | Laser Diffraction | Analyzes solid particle size distribution in suspension using Mie scattering principles. |
| Microbial Limits | Membrane Filtration | Detects aerobic microorganisms by filtration, membrane transfer to culture media, and colony enumeration. |
