Keep Cold. Moisture Sensitive. Air Sensitive. Store under Argon.
Miscible and reacts violently with water.


Borane-tetrahydrofuran complex is an important reagent used in the reduction of certain functional groups viz. aldehyde, ketone, carboxylic acid, amide, oxime, imine and nitrile. It is also used as hydro borating agent. It acts as a borane source for oxazaborolidine catalyzed asymmetric reductions. It is utilized to reduce nylon surface amide groups to secondary amines.


Air and moisture sensitive. Forms explosive peroxides in contact with air. Incompatible with acids, acid chlorides, acid anhydrides, oxidizing agents and alcohols. On hydrolysis, it forms hydrogen and boric acid.
