Description

Dnp-Peg3-Dnp CAS NO 1365655-92-0 is a specialized bifunctional PEG-based linker compound featuring dinitrophenyl (DNP) protecting groups. This compound matters as a critical reagent in advanced organic synthesis and bioconjugation, enabling the controlled assembly of complex molecular architectures. It is primarily needed by researchers and manufacturers in the pharmaceutical, biotechnology, and advanced materials sectors for developing novel drug delivery systems, diagnostic probes, and functional polymers.

Application

• Bioconjugation and Crosslinking: Used as a heterobifunctional linker for coupling peptides, proteins, or antibodies to other biomolecules, surfaces, or nanoparticles.
• Prodrug Synthesis: Serves as a cleavable spacer in the design of prodrugs, where the DNP groups can be selectively removed to release an active pharmaceutical ingredient (API).
• Polymer Chemistry: Acts as a functional monomer or chain extender in the synthesis of stimuli-responsive and biodegradable polymers for biomedical applications.
• Protecting Group Strategy: The DNP groups provide orthogonal protection for amines in multi-step synthetic routes, particularly in peptide and oligonucleotide synthesis.
• Diagnostic Reagent Development: Employed in the fabrication of assay components and diagnostic labels where controlled linkage and subsequent release are required.
• Material Science: Used to functionalize surfaces and materials with bioactive molecules for tissue engineering and biosensor applications.

Quality Control

Our Dnp-Peg3-Dnp is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) with detailed chromatographic data are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C or as indicated on the label or COA. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
