Industrial Applications of 200190-89-2
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D and Manufacturing | Protective intermediate in peptide synthesis for preparing therapeutic peptides or protein drugs containing arginine residues | Used in solid-phase or liquid-phase peptide synthesis (SPPS/LPPS); the PBF group protects the guanidino moiety, typically as the cyclohexylamine salt to enhance stability and solubility, facilitating subsequent deprotection and purification steps |
Manufacturing Quality Control of 200190-89-2
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 205 nm, comparing peak area to certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities by gradient HPLC-UV, using relative response factors or external standards. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, ethyl acetate) via headspace GC with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration using iodine generation in pyridine-free reagent system. |
| Heavy Metals | ICP-MS | Quantifies trace metals (Pb, Cd, Hg, As, etc.) after acid digestion, using inductively coupled plasma mass spectrometry. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| Sulfate Content | Ion Chromatography | Separates and quantifies sulfate ions using suppressed conductivity detection after aqueous extraction. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled high-temperature ashing and weighing. |
| Optical Rotation | Polarimetry | Measures specific rotation using sodium D-line light to confirm chiral integrity and enantiomeric purity. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines pH of a defined suspension or solution using calibrated glass electrode and pH meter. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry or wet dispersed sample to determine volume-based particle size distribution. |
| Microbial Limits | Membrane Filtration | Detects aerobic microorganisms, yeasts, and molds using membrane filtration followed by incubation on selective agar media. |
