Industrial Applications of D-Aspartic Acid diethyl ester hydrochloride
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Used in the synthesis of antiviral agents (e.g., adefovir dipivoxil analogues) and structural modification of peptide-based drugs | Employed as a chiral building block in coupling reactions; aspartic acid residues are introduced via hydrolysis, deprotection, and related steps |
| Organic Synthesis | Applied as a chiral auxiliary or ligand precursor in asymmetric catalytic reactions | Provides a chiral environment in Diels–Alder, alkylation, and other reactions; recovered or removed after subsequent transformations |
| Agrochemicals | Serves as a potential synthetic intermediate for chiral agrochemicals (e.g., pyrethroid derivatives) | Constructs biologically active molecules containing an aspartic acid scaffold via transesterification, amidation, and related reactions |
Manufacturing Quality Control of D-Aspartic Acid diethyl ester hydrochloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (D-Aspartic Acid Diethyl Ester Hydrochloride) | Acid-Base Titration | Quantifies active compound by titration with standardized NaOH using phenolphthalein indicator; endpoint corresponds to neutralization of hydrochloride salt. |
| Water Content | Karl Fischer Titration | Measures trace water via coulometric or volumetric reaction between water and iodine generated in situ from KF reagent. |
| Residual Solvents (Ethanol, Dichloromethane) | Gas Chromatography (GC-FID) | Separates and quantifies volatile organic solvents using flame ionization detection against calibrated standards. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Detects trace metal impurities by plasma ionization followed by mass spectrometric quantification at element-specific m/z ratios. |
| Chloride Content | Potentiometric Titration | Determines chloride ions using silver nitrate titrant and silver/silver chloride electrode; endpoint detected by potential inflection. |
| Optical Rotation | Polarimetry | Measures specific rotation at 20 C and 589 nm to confirm chiral integrity and enantiomeric purity of D-isomer. |
| Related Substances | HPLC-UV | Separates and quantifies structurally related impurities (e.g., monoester, free acid, L-isomer) using reversed-phase C18 column and UV detection at 210 nm. |
| pH (1% w/v aqueous solution) | pH Potentiometry | Determines acidity of aqueous solution using calibrated glass electrode and pH meter under controlled temperature. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (700-800 C) and precise weighing. |
| Microbial Limits | Membrane Filtration | Quantifies aerobic mesophilic bacteria and molds/yeasts by filtration, membrane transfer to selective agar, and colony enumeration. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry powder particle size distribution by measuring angular scattering pattern of laser beam passing through dispersed sample. |
| Appearance (Color and Clarity) | Visual Inspection | Assesses physical state, color (white to off-white), and absence of visible particulates or cloudiness in solution or solid form. |
