Industrial Applications of N-CARBOBENZOXY-D-LEUCINE DICYCLOHEXYLAMMONIUM SALT
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Industry | Chiral resolving agent for preparing optically pure D-leucine and its derivatives | Used as a chiral auxiliary in diastereomeric crystallization to form diastereomeric salts with racemic acids, enabling resolution via solubility differences |
| Organic Synthesis | Chiral protecting group carrier, providing an N-Cbz-protected D-leucine building block | Employed in the construction of precursors for solid-phase peptide synthesis (SPPS); the dibenzylamine salt form enhances crystallinity and purification efficiency, followed by hydrogenolytic removal of the Cbz group |
Manufacturing Quality Control of N-CARBOBENZOXY-D-LEUCINE DICYCLOHEXYLAMMONIUM SALT
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 210-230 nm, calibrated against certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time comparison and peak area normalization. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., methanol, ethyl acetate, toluene) against external calibration standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content via stoichiometric reaction. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and others after acid digestion, using plasma excitation and optical emission detection. |
| Residue on Ignition | Gravimetric Analysis | Measurement of inorganic ash content after high-temperature incineration (500-600 C) and precise weighing of residual residue. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line light to confirm chiral integrity and enantiomeric purity. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Determination of pH in a defined suspension (e.g., 1% w/v in water) using calibrated glass electrode and pH meter. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample by measuring angular scattering intensity of laser beam to calculate size distribution. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, using calibrated capillary method per USP <741>. |
| Chloride Content | Ion Chromatography | Quantification of chloride ions after aqueous extraction using anion-exchange column and suppressed conductivity detection. |
| Microbial Limits | Membrane Filtration and Culture | Enumeration of aerobic microorganisms and detection of specified pathogens (e.g., E. coli, S. aureus) per pharmacopeial methods. |
