Used in solid-phase oligonucleotide synthesis to introduce a benzoyl-protected riboadenine base into RNA strands. Enables the construction of custom RNA sequences for applications in molecular biology, genetic research, and diagnostics. The phosphoramidite group allows for efficient coupling under automated synthesis conditions, making it essential in the production of RNA primers, probes, and synthetic RNAs. Commonly used in pharmaceutical development and genomic studies where precise nucleotide sequences are required.
