Industrial Applications of N-Cbz-L-Threonine
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Synthetic intermediate for antiviral drug manufacturing | Reacts with other compounds to form key structural elements of the target drug molecule |
| Biochemical Research | Amino-protecting group in peptide synthesis | Temporarily protects amino groups during solid-phase or solution-phase peptide synthesis to prevent undesired side reactions; subsequently removed via hydrogenolysis or other deprotection methods |
| Cosmetics | Ingredient in skin care products | Mixed with other active ingredients prior to incorporation into the final formulation, potentially contributing moisturizing or other skin care functions |
| Food Additives | Potential source of food-grade amino acids | Converted into edible forms via enzymatic reactions or other methods; safety evaluation and regulatory compliance must be confirmed |
| Research Reagents | Reference standard or analytical standard in laboratories | Used directly in analytical testing or scientific research after precise weighing and dissolution |
Manufacturing Quality Control of N-Cbz-L-Threonine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a reference standard using reversed-phase chromatography and UV detection at 210 nm. |
| Chiral Purity | Chiral HPLC | Separation of L- and D-enantiomers on a chiral stationary phase, with quantification based on peak area ratio. |
| Loss on Drying | Gravimetric (Oven Drying) | Mass loss measured after drying sample at 105 C for 2 hours under atmospheric pressure. |
| Residue on Ignition | Gravimetric (Sulfated Ash) | Mass of inorganic residue remaining after controlled ignition at 700-800 C following sulfuric acid treatment. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion and plasma emission spectroscopy. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode; endpoint detected by potential inflection. |
| Sulfate Content | Turbidimetry | Formation of barium sulfate precipitate in acidic medium; quantification via light scattering measurement. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light at 20 C using sodium D-line (589 nm) in solution. |
| pH of Solution | Potentiometric pH Measurement | Determination of hydrogen ion activity in a 1% aqueous solution using calibrated glass electrode. |
| Related Substances | HPLC-UV | Detection and quantification of structurally related impurities (e.g., N-Cbz-threonine lactone, deprotected threonine) using gradient RP-HPLC. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric determination of water based on iodine-sulfur dioxide reaction in pyridine-methanol medium. |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic mesophilic microorganisms and detection of specified pathogens per pharmacopeial methods. |
