Tris(3,6-dioxaheptyl)amine acts as a phase transfer catalyst used in the preparation of 1,3-dideaza-2'-deoxyadenosine and related benzimidazole 2'-deoxyribonucleosides. It is also used as an intermediate in the synthesis of telithromycin. Further, it is used in the oxidation of arylmethanols under phase-transfer conditions. In addition to this, it acts as a cryptand during phase-transfer glycosylation of 2-amino-4-methoxy-7H-pyrrolo[2,3-d]pyrimidine.

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.
