Description

Di-Boc-Seleno-L-Cystine is a protected, organoselenium derivative of the amino acid L-cystine, specifically designed for advanced peptide synthesis and biochemical research. This compound is crucial for the controlled introduction of selenium into peptide backbones, enabling the study of selenoproteins and the development of novel bioactive molecules. It is an essential building block for pharmaceutical researchers, peptide chemists, and biotechnology companies focused on redox biology, enzyme mimics, and therapeutic peptide development.

Application

• Peptide Synthesis: A key protected intermediate for the solid-phase and solution-phase synthesis of selenocysteine-containing peptides and selenoproteins.
• Biochemical Research: Used in studies investigating the role of selenium in antioxidant enzymes like glutathione peroxidase and in redox signaling pathways.
• Pharmaceutical Development: Serves as a precursor for developing novel therapeutic agents that leverage the unique chemical properties of selenium.
• Proteomics & Labeling: Potential use in the site-specific labeling of proteins for structural and functional analysis via selenium-based probes.
• Material Science: Exploration of selenium-containing polymers and biomaterials with specialized electronic or catalytic properties.
• Reference Standard: Acts as a high-purity analytical standard for quality control and method development in analytical laboratories.

Quality Control

Our Di-Boc-Seleno-L-Cystine is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and chiral analysis to ensure enantiomeric purity. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all critical quality attributes to support your research and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C (refrigerated) or as indicated on the label or COA. This product is hygroscopic (moisture-sensitive) and should be handled under anhydrous conditions to maintain stability and purity. Allow the container to reach room temperature before opening to minimize moisture condensation.
