420-90-6 Usage

General Description

3-Bromo-3,3-difluoropropene is a chemical compound made up of carbon, hydrogen, bromine, and fluorine atoms. It is an organic compound that falls into the category known as halogenated propenes. Major attributes of this chemical include its stability, reactivity under different conditions, and the presence of polar bonds resulting from the halogens. However, in its pure form, it has potential risks, as exposure to this chemical may lead to health hazards, like eye irritation or issues with the respiratory system. Yet, these risks are mainly related to industrial or laboratory settings, where it is used for various chemical reactions due to its reactivity.

Check Digit Verification of cas no

The CAS Registry Mumber 420-90-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 420-90:
(5*4)+(4*2)+(3*0)+(2*9)+(1*0)=46
46 % 10 = 6
So 420-90-6 is a valid CAS Registry Number.

The infrared spectra (3200-50 cm-1) of gaseous and solid and Raman spectra (3200-10 cm-1) of the liquid with qualitative depolarization ratios and solid 3-bromo-3,3-difluoropropene CH2=CHCBrF2 have been recorded

Seyferth,Simon,Sepelak,Klein

, p. 4634 - 4639 (2007/10/02)

gem-(Difluoroallyl)lithium may be generated by lithium-bromine exchange between n-butyllithium and CH//2 equals CHCF//2Br at minus 95 degree C by using an in situ procedure. When this preparation is carried out in the presence of chlorosilanes, aldehydes, ketones, and esters, products are formed, often in good yield. The factors determining the regioselectivity in addition to C equals O of unsymmetrically substituted allylic lithium reagents are discussed.
