应用
1,3-Dichloro-1,1,3,3-tetraisopropyldisiloxane is a silylating reagent used for simultaneous protection of 3'- and 5'-hydroxy functions of ribonucleosides. It is used in the analysis of Watson-Crick and Hoogstein base pairing in nucleotides. It is also employed in the formation of ribavirin chemical delivery systems. Further, it serves as a protecting group reagent for open-chain polyhydroxy compounds. In addition to this, it is involved in the preparation of cyclic bridged peptides. 备注
