1,3-Dichloro-1,1,3,3-tetraisopropyldisiloxane, 97%, Thermo Scientific Chemicals

Description

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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
