What is DAST?
DAST, also known as Diethylaminosulfur Trifluoride, is a reactive fluorinating reagent widely used in organic synthesis, fluorine chemistry, pharmaceutical intermediate development, and other research involving selective fluorination. Its CAS number is 38078-09-0, with the molecular formula C4H10F3NS and molecular weight of 161.19 g/mol.
DAST is a liquid at room temperature and is commonly supplied as a high-purity chemical reagent. It is especially useful when a synthesis route requires the conversion of selected oxygen-containing functional groups into fluorinated structures. For example, DAST can react with alcohols to form alkyl fluorides, while reactions with aldehydes and ketones can be used to introduce gem-difluoro functionality. These properties make DAST CAS 38078-09-0 relevant to research involving fluorinated organic compounds, pharmaceutical intermediates, and specialty chemical synthesis.
From a procurement perspective, DAST is different from ordinary bulk chemical materials. Moisture control, packaging integrity, batch consistency and transportation conditions all matter. The material is moisture-sensitive and reacts with water, so appropriate handling and storage procedures should be followed according to the applicable SDS and product specification.
Typical Applications
- Organic synthesis: Used as a fluorinating reagent in synthetic chemistry.
- Alcohol fluorination: Used to convert suitable alcohol functional groups into corresponding fluorinated compounds.
- Carbonyl fluorination: Can be used with aldehydes and ketones for the preparation of fluorinated products.
- Pharmaceutical intermediate research: Useful in synthetic routes where fluorine substitution is required.
- Fluorine-containing compound development: Applied in research and process development involving fluorinated organic molecules.
- Specialty chemical synthesis: Suitable for laboratories and manufacturers developing fluorinated intermediates and advanced organic molecules.
