| Biotechnology | Protein engineering | Used to construct recombinant proteins or functionalized peptide chains with specific modifications |
| Advanced Materials | Synthesis of functional polymers | Acting as a nitrogen-containing functional monomer in the design of bioactive smart materials or nanocarriers |
Manufacturing Quality Control of Fmoc-Lys(Boc)-OH
| Detection Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, physical form (typically white to off-white crystalline powder), and check for foreign particles or moisture absorption and caking. |
| Purity | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with UV detection (e.g., 220 nm); calculate main peak purity using area normalization or external standard method. |
| Specific Rotation | Polarimeter Measurement | Dissolve the sample in specified solvent (e.g., DMF or ethanol), then measure optical rotation at a defined wavelength (e.g., 589 nm) and temperature. |
| Melting Point | Capillary Melting Point Apparatus | Determine the melting temperature range to assess crystallinity and thermal stability (typical value: approximately 120–130°C). |
| Water Content | Karl Fischer Titration | Measure water content using coulometric or volumetric Karl Fischer method; ensure compliance with loss on drying requirements (generally <1.0%). |
| Residual Solvents | Gas Chromatography (GC) | Use headspace or direct injection, capillary column separation, and FID detector to quantify residual organic solvents (e.g., DCM, DMF, etc.). |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, determine total levels of lead, arsenic, mercury, cadmium, and other heavy metals; ensure compliance with pharmacopoeial limits (e.g., <20 ppm). |
| TLC Spot | Thin Layer Chromatography (TLC) | Use silica gel plates, development system (e.g., CH₂Cl₂:MeOH = 9:1), and visualizing agents (e.g., ninhydrin or UV 254 nm) to observe a single spot. |
| pH (Solution) | pH Meter Measurement | Dissolve the sample in water or a specified buffer solution, then measure pH to evaluate acidic/basic impurities (typically pH 4.5–6.5). |
| Residue on Ignition | Ignition in Muffle Furnace | After high-temperature ashing, weigh the residue to assess inorganic salts or metal oxide content (generally <0.1%). |
| Single Impurity and Total Impurities | HPLC (Gradient Elution) | Use gradient elution program to separate individual impurity peaks; calculate impurity limits using self-reference method or area normalization. |
