Packing Group Ⅰ
Bis(2-Methoxyethyl)aminosulfur Trifluoride (BAST) (CAS: 202289-38-1), abbreviated as BAST, versatile, thermally stable nucleophilic fluorinating reagent.
BAST is a fluorinated reagent, easy hydrolysis to produce HF, so in the use of the same as the use of hydrofluoric acid and its ammonium salt, special attention should be paid. When a higher temperature is required due to the reactivity of the substrate, a safer BAST(Deoxofluor) can be selected, which only slowly decomposes during heating without explosion.
BAST is used as an organic intermediate and a pharmaceutical intermediate, can be used in laboratory research and development process and chemical and pharmaceutical synthesis process.
Reactant for: Fluorination reactions; Preparation of fluorinated catechols via Umpolung based nucleophilic deoxyfluorination; Preparation of imidazole derivatives as CXCR3 antagonists; Ring expansion reactions; Synthesis of acyl azides from carboxylic acids; Aldehydes or ketones from carboxylic acids and Grignard reagents via in situ generation of Weinreb amides.
