402-31-3 Usage
Chemical Properties
CLEAR COLOURLESS LIQUID
Uses
1,3-Bis(trifluoromethyl)benzene undergoes regioselective metalation and subsequent carboxylation at position 2 to give 2,6-bis(trifluoromethyl)benzoic acid. a convenient, selective synthesis of bis[2,4-bis(trifluoromethyl)phenyl]phosphane derivatives with 1,3-bis(trifluoromethyl)benzene as starting material.
General Description
Lithiation reaction of 1,3-bis(trifluoromethyl)benzene has been investigated. 1,3-Bis(trifluoromethyl)benzene undergoes regioselective metalation and subsequent carboxylation at position 2 to give 2,6-bis(trifluoromethyl)benzoic acid.
Check Digit Verification of cas no
The CAS Registry Mumber 402-31-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,0 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 402-31:
(5*4)+(4*0)+(3*2)+(2*3)+(1*1)=33
33 % 10 = 3
So 402-31-3 is a valid CAS Registry Number.
InChI:InChI=1/C7H4Cl3F/c8-7(9,10)5-1-3-6(11)4-2-5/h1-4H
