Tris(methoxy)borane*NH3, also known as borane trimethyl ether complex or borane-tetrahydrofuran complex, is a colorless, volatile, and flammable liquid. It is a complex of borane (BH3) and ammonia (NH3), where borane is a strong Lewis acid and ammonia acts as a Lewis base. tris(methoxy)borane*NH3 is widely used as a reducing agent in organic synthesis, particularly for the reduction of carbonyl compounds to alcohols, and in the preparation of various organoborane compounds. It is also employed as a reagent in the synthesis of pharmaceuticals and agrochemicals. Due to its high reactivity and potential hazards, tris(methoxy)borane*NH3 must be handled with care, using appropriate safety measures and equipment.
The CAS Registry Mumber 66794-43-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,7,9 and 4 respectively; the second part has 2 digits, 4 and 3 respectively. Calculate Digit Verification of CAS Registry Number 66794-43: (7*6)+(6*6)+(5*7)+(4*9)+(3*4)+(2*4)+(1*3)=172 172 % 10 = 2 So 66794-43-2 is a valid CAS Registry Number.
