540-87-4 Usage
General Description
1,1,1-Trifluoro-3-iodobutane, also known as trifluoroiodobutane, is a chemical compound with the molecular formula C4H7F3I. It is a colorless, odorless liquid with a high boiling point and low volatility. 1,1,1-TRIFLUORO-3-IODOBUTANE is commonly used as a building block and reagent in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It is known for its ability to introduce the trifluoromethyl group and the iodo functional group into organic molecules, making it a valuable tool in the field of organic chemistry. Additionally, it is also used as a solvent and as an intermediate in the production of other fluorinated compounds. However, due to its high reactivity and potential hazard to human health and the environment, it must be handled with care and in accordance with safety regulations.
Check Digit Verification of cas no
The CAS Registry Mumber 540-87-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,4 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 540-87:
(5*5)+(4*4)+(3*0)+(2*8)+(1*7)=64
64 % 10 = 4
So 540-87-4 is a valid CAS Registry Number.

Addition of Free Radicals to Unsaturated Systems. Part 24. Kinetics and Mechanism of the Gas-phase Thermal Reactions of Trifluoroiodomethane with Propene

, p. 1713 - 1718 (2007/10/02)
The gas-thermal addition of trifluoroiodomethane to propene, at temperatures of 533-583 K, reactant ratios from 1:1 to 4:1, and total pressures of 100-300 mmHg, is shown to be a free-radical chain reaction with the kinetic equation as shown below.It is concluded that initiation is by the reaction of d/dt=k82>0.253I>1.093H6>0.41 iodine atoms, in thermal equilibrium with molecular iodine, with trifluoroiodomethane, and termination is predominantly by reactions involving trifluorobutyl radicals.The Arrhenius parameters found for k8 are discussed in terms of those for the elementary reactions involved on the basis of the proposed mechanism.
