Cis-Cyclobutane-1,2-dicarbonitrile is a cyclic organic compound with the molecular formula C6H8N2. It features a four-membered carbon ring with two carbon-carbon double bonds and two nitrile groups (C≡N) attached to adjacent carbon atoms. CIS-CYCLOBUTANE-1,2-DICARBONITRILE is known for its unique strained ring structure, which results from the bond angles being significantly different from the ideal tetrahedral angles. Due to its strained nature, cis-cyclobutane-1,2-dicarbonitrile is less stable than its trans isomer and can undergo various chemical reactions, such as ring-opening polymerization, to form useful materials. It is also of interest in the field of organic chemistry for its potential applications in the synthesis of other cyclic compounds and as a model system for studying the effects of ring strain on chemical reactivity.

3211-19-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3211-19-6 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, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3211-19:
(6*3)+(5*2)+(4*1)+(3*1)+(2*1)+(1*9)=46
46 % 10 = 6
So 3211-19-6 is a valid CAS Registry Number.

Novel synthesis method of lobaplatin intermediate

-

, (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.
