Physical & Chemical Properties

DAST is a homogeneous oily liquid with stable activity under low-temperature sealed conditions. It is miscible with conventional organic solvents and decomposes in contact with water, avoiding aqueous environment in application. The reagent delivers outstanding selective fluorination performance, effectively realizing fluorination of alcohols, ketones and carboxylic acid derivatives without damaging main molecular structures. It has moderate reaction rate and high conversion rate, with stable reagent purity and low impurity content. Strict temperature control is required during usage and storage to prevent thermal decomposition and ensure reaction accuracy and safety.

Main Applications

It is mainly used as a professional fluorinating reagent in organic chemistry and pharmaceutical industry. It is applicable for the synthesis of fluorinated pharmaceutical intermediates, preparation of fine fluorine chemicals and laboratory organic fluorination experiments. It can efficiently complete substitution fluorination reactions, greatly improving the synthesis efficiency of fluorine-containing active compounds, and is an essential reagent in modern pharmaceutical and fine chemical research.
