DMT-2'Fluoro-DG(IB) Amidite; (2R,3R,4R,5R)-2-((bis(4-methoxyphenyl)(phenyl)methoxy)methyl)-4-fluoro-5-(2-isobutyramido-6-oxo-1,6-dihydro-9H-purin-9-yl)tetrahydrofuran-3-yl (2-cyanoethyl) diisopropylphosphoramidite; CAS No.: 144089-97-4;DMT-2'Fluoro-DG(IB) Amidite. PROPERTIES: DMT-2'Fluoro-DG(IB) Amidite is a white to pale yellow solid with a molecular formula of C55H56F6N9O8 and a molecular weight of 1125.07 g/mol. It exhibits limited aqueous solubility but dissolves well in common organic solvents like dichloromethane and tetrahydrofuran. Proper storage requires maintaining it at -20 C in a sealed amber vial protected from light and moisture. When handling, chemical-resistant gloves and eye protection are essential due to its potential to cause skin and eye irritation. APPLICATIONS: DMT-2'Fluoro-DG(IB) Amidite is a phosphoramidite building block used in oligonucleotide synthesis. In medicinal chemistry, it enables incorporation of 2'-fluoro-modified ribonucleotides into synthetic oligonucleotides, enhancing their stability and binding affinity (source: Nucleic Acids Research). The compound's unique chemical structure facilitates automated DNA/RNA synthesis processes, particularly in developing antisense therapeutics and siRNA molecules. Additionally, it serves as a research tool for studying RNA structure-function relationships and improving nucleic acid-based diagnostic probes (source: Bioconjugate Chemistry).
