| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Amino acid protecting reagent for temporary protection of the lysine side-chain amino group in peptide synthesis | Prepared via reaction of isocyanate with 6-aminohexylamine in solid-phase peptide synthesis (SPPS), followed by coupling to the carboxyl group of the target amino acid or peptide chain; the tert-butoxycarbonyl (Boc) group is selectively removed under acidic conditions (e.g., TFA) |
| Organic Synthesis | Multifunctional amino-based linker for constructing PROTAC molecules, antibody–drug conjugate (ADC) linkers, and targeted probes | Used as a spacer to connect the target protein ligand and the E3 ligase ligand (in PROTACs) or to link the antibody and cytotoxic payload (in ADCs); typically incorporated into the molecular scaffold via amidation, urea formation, or thiourea formation |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 200-220 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and detection of impurities by gradient HPLC-UV; identification and quantification against reference standards or threshold-based reporting. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify volatile organic solvents (e.g., THF, DMF, toluene) based on retention time and calibration curves. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content via stoichiometric reaction with water. |
| Residual Metals (e.g., Pd, Ni, Fe) | ICP-MS | Multi-element quantification after acid digestion using inductively coupled plasma mass spectrometry for ultra-trace metal impurities. |
| Chloride Content | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous extract; quantified against chloride standard calibration. |
| Heavy Metals (Total) | AAS (Flame or Graphite Furnace) | Acid digestion followed by atomic absorption spectroscopy to measure total heavy metals (e.g., Pb, Cd, Hg) as sulfide precipitate limit test equivalent. |
| Optical Rotation | [alpha]D Measurement | Determination of specific optical rotation using sodium D-line light source to confirm chiral integrity and absence of racemization. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition analysis by observing solid-to-liquid phase change in capillary tube under controlled heating rate. |
| Loss on Drying | Gravimetric (105 C, 2 h) | Weight loss measurement after drying under standardized temperature and time to determine volatile and moisture content. |
| pH of Aqueous Solution | pH Meter | Measurement of hydrogen ion activity in a defined aqueous suspension or solution using calibrated glass electrode. |
| Residual tert-Butyl Carbamate | GC-MS | Detection and quantification of thermal decomposition product (tert-butyl carbamate) using gas chromatography coupled with mass spectrometry. |
