Industrial Applications of H-D-DAP-OH HCL
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Structural building block for synthesizing antibiotics (e.g., polymyxins) and anticancer agents | Used as a chiral building block, incorporated into the target molecular scaffold via condensation, cyclization, and related reactions |
| Organic Synthesis | Precursor to chiral ligands or catalysts | Processed into chiral complexes for asymmetric catalysis by coordination with metal salts |
| Biochemical Research | Reagent for incorporating non-natural amino acids in protein engineering | Employed as a modified amino acid in solid-phase peptide synthesis (SPPS) to study enzyme active sites or protein folding |
Manufacturing Quality Control of H-D-DAP-OH HCL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (D-2,3-Diaminopropionic Acid Hydrochloride) | Acid-Base Titration | Quantifies main component by titration with standardized NaOH using mixed indicator or potentiometric endpoint detection. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric reaction between water and iodine in pyridine/methanol medium. |
| Optical Rotation | Polarimetry | Determines enantiomeric purity by measuring rotation of plane-polarized light in solution at specified concentration and wavelength. |
| Heavy Metals | ICP-OES | Quantifies trace metal impurities (e.g., Pb, Cd, Ni) by plasma excitation and elemental emission spectroscopy. |
| Chloride Impurity | Potentiometric Titration | Detects chloride ions using silver nitrate titrant with silver-sulfide electrode for endpoint detection. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing at 700-800 C. |
| pH (1% aqueous solution) | pH Meter Measurement | Determines acidity/basicity of aqueous solution using calibrated glass electrode system. |
| Related Substances | HPLC-UV | Separates and quantifies structurally related impurities using reversed-phase chromatography with UV detection at 200-220 nm. |
| Loss on Drying | Thermogravimetric Analysis | Measures volatile content loss under controlled temperature (105 C) and vacuum or nitrogen purge. |
| Specific Absorbance (UV) | UV-Vis Spectrophotometry | Evaluates optical purity and absence of chromophoric impurities by absorbance measurement at specified wavelength. |
| Sulfated Ash | Gravimetric Analysis | Determines inorganic sulfate residue after ignition with sulfuric acid treatment and subsequent weighing. |
| Microbial Limits | Membrane Filtration | Assesses total aerobic microbial count and absence of specified pathogens per pharmacopeial procedures. |
