CAS 38078-09-0: (Diethylamino)sulfur trifluoride

Diethylaminosulfur trifluoride (DAST) is a reactive chemical that can be used as a methylating agent. It reacts with the hydroxyl group of carotenoids, including β-carotene, to produce x-ray crystal structures with the alcohol methanol solvent. DAST also reacts with 6alkyl and methyl glycosides, such as sucrose, producing a hydroxy derivative. DAST has been shown to have carcinogenic properties in tumor cell lines and is able to induce apoptosis in these cells by damaging their DNA. The use of DAST for cancer treatment can be done through laser ablation or injection into tumors.

Diethylaminosulfur trifluoride (DAST) is used as a precursor to prepare 2,6-dimethoxybenzoyl fluoride and 2-thiazolines. It is a useful fluorinating agent used for a variety of compounds including alcohols, thioethers, alkenols and cyanohydrins. It also serves as a catalyst for Friedel-Crafts allylation reaction using tertiary cyclopropyl silyl ethers and in the rearrangement of homoallylic alcohols to unsaturated aldehydes. It plays an important role for gem difluorination of ketopipecolinic acids. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio.
