Widely used in solid-phase oligonucleotide synthesis, this compound acts as a phosphitylating agent to form phosphoramidite monomers. It enables efficient and selective coupling to nucleosides, facilitating the construction of DNA and RNA sequences with high yield and purity. Its diisopropylamino group enhances stability and reactivity control during synthesis, making it valuable in the production of primers, probes, and synthetic genes for molecular biology, diagnostics, and gene therapy applications.
