| Industry | Application | Process Description |
|---|---|---|
| Pharmaceuticals | Pharmaceutical Intermediates | Used as an intermediate in the synthesis of peptide-based drugs, such as anticoagulants and immunomodulators |
| Biochemistry | Peptide Synthesis | Applied as a protected amino acid derivative in solid-phase or solution-phase peptide synthesis |
| Agriculture | Plant Growth Regulators | Employed in the synthesis of biologically active plant growth-regulating compounds |
| Research | Biochemical Reagents | Utilized in enzymatic reaction studies, protein structure-function analysis, and related experiments |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (D-Arginine methyl ester hydrochloride) | Acid-base titration with NaOH | Quantitative neutralization of HCl salt using standardized sodium hydroxide solution, with potentiometric or visual endpoint detection. |
| Chiral Purity (enantiomeric excess) | Chiral HPLC | Separation of D- and L-enantiomers on a chiral stationary phase followed by UV detection and peak area comparison. |
| Water Content | Karl Fischer titration | Electrochemical titration using iodine, sulfur dioxide, and base in methanol to quantify water via stoichiometric reaction. |
| Residual Solvents (methanol, ethyl acetate) | Gas Chromatography (GC-FID) | Separation and quantification of volatile organic solvents using flame ionization detection against calibrated standards. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element detection and quantification based on mass-to-charge ratio after acid digestion and plasma ionization. |
| Chloride Content | Potentiometric titration with AgNO3 | Precipitation of chloride as AgCl with silver nitrate, detected by silver electrode potential change. |
| pH (1% aqueous solution) | pH meter measurement | Direct measurement of hydrogen ion activity in aqueous solution using calibrated glass electrode system. |
| Related Substances | Reverse-phase HPLC with UV detection | Separation of impurities and degradation products on C18 column, quantified by UV absorbance at 200–220 nm. |
| Loss on Drying (LOD) | Gravimetric analysis (105 C, 2 h) | Mass loss upon controlled heating under standard conditions, indicating volatile content including residual solvents and moisture. |
| Appearance (color and clarity) | Visual inspection against USP standards | Comparison of sample solution (e.g., 5% w/v in water) to reference standards for color (APHA) and particulate clarity. |
| Sulfated Ash | Gravimetric ash analysis | Combustion at 600 C followed by sulfuric acid treatment and final weighing to determine inorganic residue content. |
