FAQ's of 5'-O-(4,4'-dimethoxytrityl) 2'-O-[(1,1-dimethylethyl)-dimethylsilyl] N6- benzoyl Adenosine:
Q: How is 5-O-(4,4-dimethoxytrityl) 2-O-[(1,1-dimethylethyl)-dimethylsilyl] N6-benzoyl Adenosine used in oligonucleotide synthesis?
A: This compound serves as a protected adenosine monomer, providing specific protection for the 2-O and 5-O hydroxyl groups and the N6 position. Its design enables selective deprotection and coupling cycles critical to efficient RNA and DNA synthesis on solid-phase supports.
Q: What are the recommended deprotection conditions for each protective group on this molecule?
A: For this derivative, the DMT group is removed using mild acid; the TBDMS group requires a fluoride source such as TEA3HF or TBAF, and the N6-benzoyl group is cleaved with ammonia or methylamine. These conditions should be used sequentially to ensure selective removal.
Q: When should I store and handle this compound under an inert atmosphere?
A: It is essential to handle and store this compound under dry, inert gas (such as nitrogen or argon) at -20C, particularly to protect it from moisture and light, as the compound is moisture sensitive and stability may be compromised under ambient conditions.
Q: Where is this product typically applied in the laboratory?
A: This product is primarily used in research settings for the chemical synthesis of DNA and RNA oligonucleotides, especially where high purity and controlled protection/deprotection strategies are required, such as in molecular biology labs or specialized synthesis facilities.
Q: What are the main benefits of using this protected adenosine monomer?
A: The principal benefits include high purity (>98%), precise functional group protection, low endotoxin and heavy metal content, and compatibility with common oligonucleotide synthesis chemistries, ensuring reliable, high-quality results in sensitive applications.
Q: Is this compound hazardous, and are there any special precautions for disposal?
A: According to GHS classification, this product is non-hazardous. Normal laboratory safety protocols should be observed, and disposal should follow institutional chemical waste guidelines, avoiding release into the environment.
Q: How long is the shelf life and under what conditions should it be stored?
A: The shelf life is two years when the product is stored at -20C, well-sealed, and shielded from moisture and light. Proper storage preserves stability and ensures continued suitability for research and synthesis.
