| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Used as a pharmaceutical intermediate in the synthesis of biologically active compounds, such as antihypertensive and cardiovascular drugs | Organic synthesis, peptide synthesis |
| Biochemical Research | Applied in studies of the urea cycle, nitric oxide metabolism, and related enzymes (e.g., arginase, nitric oxide synthase) | Enzymatic analysis, metabolic pathway investigation |
| Nutrition & Dietary Supplements | Formulated as a dietary supplement ingredient to support vascular health and exercise performance (often combined with other amino acids, such as arginine) | Formulation blending, microencapsulation |
| Cosmetics | Used as a skin-conditioning or moisturizing agent, leveraging its amino acid derivative properties to enhance skin barrier function | Emulsification, aqueous-phase dissolution, formulation stabilization |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at 200-210 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and detection of structurally similar impurities using gradient HPLC-UV; identification and quantification relative to main peak. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify volatile organic solvents based on retention time and peak area calibration. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content via stoichiometric reaction. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, using mass spectrometry for ultra-trace detection. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride anion using suppressed conductivity detection after eluent gradient separation. |
| Sulfate Impurity | Ion Chromatography | Separation and quantification of sulfate anion using suppressed conductivity detection following sample filtration and dilution. |
| pH (1% aqueous solution) | Potentiometric pH Measurement | Measurement of hydrogen ion activity in a standardized aqueous solution using calibrated glass electrode and pH meter. |
| Specific Optical Rotation | Polarimetry | Determination of chiral purity by measuring the angle of rotation of plane-polarized light through a solution at specified concentration and temperature. |
| Residue on Ignition | Gravimetric Analysis | Weighing of non-volatile residue remaining after high-temperature ashing of sample in a platinum crucible. |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic microorganisms and detection of specified pathogens (e.g., E. coli, S. aureus) using selective culture media and incubation. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or dispersed particle size distribution based on angular scattering pattern of laser beam passing through sample suspension. |
