This chemical is primarily used in the synthesis of oligonucleotides, which are essential in genetic research, diagnostics, and therapeutic applications. It serves as a key reagent in the phosphoramidite method, enabling the stepwise construction of DNA or RNA strands. Its role is crucial in producing high-purity oligonucleotides for PCR, gene editing, and sequencing technologies. Additionally, it is utilized in the development of antisense oligonucleotides and siRNA, which are important in targeted gene silencing and drug development. Its stability and reactivity make it a preferred choice in automated solid-phase oligonucleotide synthesis.
