5′-DMT-5-Fluoro-2′-deoxyuridine Phosphoramidite provides a fluorinated nucleoside building block for modified DNA synthesis and nucleic acid research and specifically combines a 5-fluoro substitution on the uracil base with a 2′-deoxyribose sugar, a 5′-O-dimethoxytrityl (DMT) protecting group, and phosphoramidite functionality for solid-phase oligonucleotide synthesis. This reagent supports site-specific incorporation of 5-fluoro-2′-deoxyuridine into synthetic DNA specifically for investigating nucleic acid structure, hybridization, and molecular recognition.
Key Features and Benefits

Storage and Handling
- Storage: Store at −20°C in a tightly sealed container under dry, inert conditions, unless otherwise specified. Protect from moisture, excessive heat, and prolonged exposure to light. Allow the sealed container to reach room temperature before opening to minimize condensation.
- Handling: Prepare solutions using anhydrous acetonitrile or another validated solvent compatible with phosphoramidite synthesis. Minimize exposure to atmospheric moisture because phosphoramidite groups are susceptible to hydrolysis.
- Use appropriate activators and coupling conditions according to the oligonucleotide synthesis protocol. Maintain anhydrous conditions during reagent preparation and automated synthesis to support coupling efficiency.
- Apply validated cleavage and deprotection procedures compatible with the 5-fluoro-2′-deoxyuridine modification and other protecting groups present in the synthesized oligonucleotide. Avoid unnecessarily harsh conditions that could compromise the integrity of modified nucleic acids.
- Confirm successful incorporation and product purity using appropriate analytical methods, such as HPLC and mass spectrometry.
5′-DMT-5-Fluoro-2′-deoxyuridine Phosphoramidite combines fluorinated pyrimidine chemistry with protected nucleoside functionality for modified DNA synthesis and specifically supports fluorinated oligonucleotide development, DNA hybridization studies, nucleic acid structure research, DNA-protein interaction studies, and molecular probe preparation.
