Industrial Applications of SELENOCYSTAMINE DIHYDROCHLORIDE
| Industry | Application | Process |
|---|---|---|
| Biopharmaceuticals | Used as a selenocysteine precursor for site-specific incorporation of selenocysteine residues into recombinant proteins to facilitate X-ray crystallographic structure determination | In expression systems such as E. coli, selenocystamine hydrochloride is metabolically converted to selenocysteine and incorporated into target proteins via engineered selenocysteine insertion sequences (SECIS) and cognate tRNA/synthetase systems |
| Organic Synthesis | Used as a selenium-containing building block for constructing selenium-containing heterocycles or selenoether functional molecules | Reduced (e.g., with NaBH₄) to release selenocysteamine, which then undergoes condensation with aldehydes/ketones or alkylation with alkyl halides to prepare selenoamino acid derivatives or selenium-catalyzed intermediates |
| Materials Science | Used as a selenium source in ligand-assisted precursor formulations for synthesizing selenide nanomaterials (e.g., Cu₂₋ₓSe, Bi₂Se₃) | In hot-injection or solvothermal processes, co-decomposed with metal precursors; thermal decomposition of selenocystamine hydrochloride generates reactive selenium species, while amine groups coordinate to modulate nanocrystal morphology and dispersion |
Manufacturing Quality Control of SELENOCYSTAMINE DIHYDROCHLORIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison with reference standard using reversed-phase chromatography and UV detection at 210 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities relative to main peak using gradient elution and UV detection. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents by gas chromatography with flame ionization detection. |
| Heavy Metals | ICP-MS | Multi-element trace metal quantification via inductively coupled plasma mass spectrometry after acid digestion. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using silver indicator electrode; endpoint detected by potential change. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric determination of water based on iodine-sulfur dioxide redox reaction in pyridine-methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Mass measurement of inorganic residue after high-temperature ashing at 700-800 C. |
| pH of Solution | pH Meter | Measurement of hydrogen ion activity in aqueous solution (1% w/v) using calibrated glass electrode. |
| Selenium Content | ICP-OES | Quantitative determination of total selenium by atomic emission spectroscopy following microwave-assisted acid digestion. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line light to assess chiral purity and identity. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder particle size via light scattering pattern generated by dispersed aerosol. |
| Microbial Contamination | Membrane Filtration | Enumeration of aerobic bacteria, yeasts, and molds after filtration and incubation on appropriate agar media. |
