1,5-Diazacycloundecane, also known as 1,5-diazabicyclo[5.4.0]undec-7-ene or DBU, is a heterocyclic organic compound with the molecular formula C8H16N2. It is a colorless, hygroscopic, and crystalline solid that is soluble in water and most organic solvents. DBU is a strong base and a weak nucleophile, commonly used as a catalyst in organic synthesis, particularly in the formation of amides, esters, and other carbonyl compounds. It is also employed as a reagent in various chemical reactions, such as deprotection, condensation, and cyclization processes. Due to its high basicity and relatively low nucleophilicity, DBU is often preferred over other strong bases like hydrazine or alkyl lithium compounds in certain reactions.

294-49-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 294-49-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,9 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.Calculate Digit Verification of CAS Registry Number 294-49:
(5*2)+(4*9)+(3*4)+(2*4)+(1*9)=75
75 % 10 = 5
So 294-49-5 is a valid CAS Registry Number.
