Industrial Applications of BENZYL N-(2-HYDROXYETHYL)CARBAMATE
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Organic synthesis intermediate | Used to protect amino groups in peptide synthesis via the benzyloxycarbonyl (Z or Cbz) protecting group; the protecting group is subsequently removed by hydrogenolysis |
| Chemical reagents | Protecting group reagent | Acts as an amino-protecting agent in coupling reactions during amino acid and peptide synthesis to prevent side reactions |
| Biochemistry | Molecular building block | Employed in the synthesis of functional molecules containing hydroxyl groups and protected amino groups; serves as a structural module in both liquid-phase and solid-phase synthesis |
Manufacturing Quality Control of BENZYL N-(2-HYDROXYETHYL)CARBAMATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 210 nm. |
| Related Substances | HPLC-UV | Separation and detection of structurally related impurities using gradient HPLC with UV monitoring; identification by retention time matching and threshold-based reporting. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., methanol, toluene, ethyl acetate) based on calibrated response factors. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generation in pyridine-free reagent; water reacts stoichiometrically with iodine and sulfur dioxide in methanol medium. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma mass spectrometry for sub-pptr detection. |
| Chloride Content | Ion Chromatography | Separation of chloride anions on an anion-exchange column with suppressed conductivity detection; quantified via external calibration curve. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after controlled high-temperature ashing (700-800 C) and weighing of the cooled crucible. |
| Optical Rotation | [alpha]D | Measurement of specific rotation using a digital polarimeter at 20 C with sodium D-line (589 nm); indicates chiral purity and enantiomeric excess. |
| pH (1% w/v aqueous solution) | Potentiometric pH Measurement | Determination of hydrogen ion activity in aqueous suspension using calibrated glass electrode and reference electrode system. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition detection by visual observation of solid-to-liquid phase change in capillary tube under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against standard references under controlled white light and defined viewing conditions. |
| Bulk Density | Tap Density Measurement | Determination of mass per unit volume after standardized mechanical tapping of a known powder mass in a graduated cylinder. |
