Used in oligonucleotide synthesis, particularly in the automated synthesis of DNA sequences. It serves as a key building block for the introduction of modified nucleosides into DNA strands, enabling the creation of custom sequences for research and therapeutic applications. Its protective groups ensure precise control during the synthesis process, allowing for the step-by-step addition of nucleotides. This compound is essential in developing antisense oligonucleotides, aptamers, and other nucleic acid-based therapeutics, as well as in genetic research and diagnostics. Its role in solid-phase synthesis makes it a critical component in producing high-purity DNA for various biotechnological and medical purposes.
