| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 210-220 nm, comparing peak area to a reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of structurally related impurities (e.g., deletion sequences, oxidation products) using gradient RP-HPLC. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on the reaction of water with iodine, sulfur dioxide, and base in methanol/pyridine medium. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection for quantification of common solvents (e.g., DMF, DCM, MeOH, EtOAc). |
| Heavy Metals | ICP-MS | Multi-element detection and quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion and dilution. |
| Optical Rotation | [alpha]D Measurement | Measurement of specific rotation using a polarimeter at 20-25 C and sodium D-line (589 nm) to confirm chiral integrity. |
| Peptide Identity | LC-MS | Confirmation of molecular weight and primary sequence via electrospray ionization LC-MS/MS fragmentation analysis. |
| Endotoxin Level | LAL Assay | Quantitative kinetic chromogenic assay measuring Limulus amebocyte lysate reaction with bacterial endotoxins. |
| Bioburden | Membrane Filtration | Enumeration of viable aerobic microorganisms by filtration, membrane transfer to agar media, and colony counting after incubation. |
| pH (1% w/v solution) | Potentiometric pH Measurement | Direct measurement using calibrated pH electrode in aqueous solution at 20-25 C. |
| Appearance | Visual Inspection | Assessment of physical form (e.g., white to off-white powder), homogeneity, and absence of visible particulates or discoloration. |
