Uses
Different sources of media describe the Uses of 20154-03-4 differently. You can refer to the following data:
1. 3-(Trifluoromethyl)pyrazole was determined to be a small compound inhibitor of human FATP2.
2. 3-(Trifluoromethyl)pyrazole may be used in copper-catalyzed pyrazole N-arylation. It may be used in the synthesis of sodium hydridotris(1H-3-trifluoromethylpyrazol-1-yl)borate by heating with sodium borohydride.
General Description
3-(Trifluoromethyl)pyrazoles is a heterocyclic building block. It undergoes alkylation with alkyl iodides in DMF to afford the N-alkyl pyrazoles. It participates in the synthesis of disubstituted pyrimidines.
Check Digit Verification of cas no
The CAS Registry Mumber 20154-03-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,1,5 and 4 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 20154-03:
(7*2)+(6*0)+(5*1)+(4*5)+(3*4)+(2*0)+(1*3)=54
54 % 10 = 4
So 20154-03-4 is a valid CAS Registry Number.

Gas-phase reactions of benzene and derivatives triggered by hydrazine/ozone; hydroxylation vs. degradation
Sol, Veronica M.,Mulder, Peter,Louw, Robert
, p. 577 - 582 (2007/10/02)
The reactions of benzene derivatives C6H5X (X = H, Cl, CH3 and CF3) with hydrazine and ozone in the dark (a source of OH radicals) have been studied in a flow reactor at ambient temperature. (Substituted) phenols were formed, but these were relatively unimportant compared to N-heterocyclic compounds (condensation products of cis-butenedial and analogues with hydrazine) and other (degradation) products.Benzene and (trifluoromethyl)benzene follow a similar path as toluene, also with oxidative ring opening as major reactions.
