694-62-2 Usage
General Description
1-CHLORO-2,3,3-TRIFLUOROCYCLOBUTENE is an organofluorine compound with the molecular formula C4H4ClF3. It is a colorless gas that is highly flammable and reactive. 1-CHLORO-2,3,3-TRIFLUOROCYCLOBUTENE is used as a refrigerant and as a precursor in the synthesis of other fluorinated compounds. It is also used in the production of pharmaceuticals, agrochemicals, and materials such as Teflon. 1-CHLORO-2,3,3-TRIFLUOROCYCLOBUTENE has a low boiling point and is commonly handled as a compressed gas or as a liquid under pressure. However, it is important to handle this compound with care due to its flammability and reactivity.
Check Digit Verification of cas no
The CAS Registry Mumber 694-62-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,9 and 4 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 694-62:
(5*6)+(4*9)+(3*4)+(2*6)+(1*2)=92
92 % 10 = 2
So 694-62-2 is a valid CAS Registry Number.

-
Paragraph 0058-0061, (2019/08/20)
The invention relates to a preparation method of halogenation cycloolefin and belongs to the field of chemical synthesis. According to the preparation method, in an amide or alkylamine solvent, with halogenation cycloparaffin as a raw material, a dehalogenation reaction is conducted, and the target product halogenation cycloolefin is obtained. According to the method, the reaction conditions are mild, the yield of the halogenation cycloolefin is high, dangerous reduction agents such as metal or hydrogen do not need to be used, the technology is safe and reliable, solid waste such as metal halide is not generated, and a common distillation means can be used for effective industrial separation.
