3211-20-9 Usage
General Description
Trans-Cyclobutane-1,2-Dicarbonitrile, also known as Bicyclo[2.2.0]butane-1,2-dicarbonitrile, is a complex chemical compound that is commonly used in organic synthesis due to its stability and reactivity. The chemical formula is C6H6N2 and its molecular weight is 106.124 g/mol. The substance exists as a pale yellow crystalline solid at room temperature and it possesses a pungent odor. It is chemically stable under standard temperatures and pressures but may decompose if exposed to heat, fire or other ignition sources due to its flammable nature. The compound has not been widely studied, but it should be handled with caution due to potential toxicity.
Check Digit Verification of cas no
The CAS Registry Mumber 3211-20-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,1 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3211-20:
(6*3)+(5*2)+(4*1)+(3*1)+(2*2)+(1*0)=39
39 % 10 = 9
So 3211-20-9 is a valid CAS Registry Number.

-
, (2021/09/22)
The invention relates to the technical field of drug synthesis, in particular to a novel synthesis method of a loxetine intermediate, which is coupled through low-toxicity dimethyl malonate as a starting raw material. The synthesis of high purity trans -1, 2 - dicyanocyclobutane is carried out after the reaction of bromination, cyclization, hydrolysis, amidation and dehydration. In addition, the yield of the product is greatly improved, so that the cost is greatly reduced, the obtained trans -1 and 2 -dicyanocyclobutane are improved in purity, the subsequent use requirements are completely met, and the market competitiveness is greatly improved.
