| Research | Scientific Research | Employed in protein chemistry and organic synthesis research |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 260-280 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. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify common organic solvents (e.g., DMF, DCM, MeOH) based on retention time and peak area. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content via stoichiometric reaction. |
| Heavy Metals | ICP-MS | Inductively coupled plasma mass spectrometry for simultaneous quantification of elemental impurities (e.g., Pb, Cd, Ni, Cu) at sub-ppb levels. |
| Residual Palladium | ICP-OES | Plasma emission spectroscopy optimized for palladium detection after acid digestion, calibrated against Pd standards. |
| Appearance | Visual Inspection | Comparison of sample color and clarity against established reference standards under controlled white light and specified viewing conditions. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid-to-liquid phase transition occurs, using calibrated digital melting point instrument. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light in solution, used to confirm identity and chiral integrity. |
| Loss on Drying | Gravimetric Analysis | Weight loss measured after drying under standardized temperature and vacuum conditions, indicating volatile content including residual solvents and moisture. |
| Related Substances | HPLC-UV | Separation and quantification of structurally related impurities (e.g., Fmoc-Gly, dipeptide byproducts) using gradient reverse-phase HPLC. |
| Residual Chloride | Ion Chromatography | Quantification of chloride ions via suppressed conductivity detection after separation on an anion-exchange column. |
