This chemical is primarily used in the synthesis of oligonucleotides, particularly in the field of molecular biology and genetic research. It serves as a protected nucleoside precursor in the solid-phase synthesis of DNA sequences. The dimethoxytrityl (DMT) group acts as a protecting group for the 5'-hydroxyl, ensuring selective coupling during the stepwise construction of DNA strands. The isobutyryl group protects the exocyclic amine of cytosine, preventing unwanted side reactions. This compound is essential in the production of custom DNA oligonucleotides for applications such as PCR, gene editing, sequencing, and the development of diagnostic tools. Its role in enabling precise and efficient DNA synthesis makes it a critical component in biotechnology and pharmaceutical research.
