2-Chloro-1-fluoro-butane is a halogenated alkane with the chemical formula C4H8ClF. It is a colorless, volatile liquid with a pungent odor. 2-chloro-1-fluoro-butane consists of a butane chain with a chlorine atom attached to the second carbon and a fluorine atom attached to the first carbon. Due to the presence of both chlorine and fluorine atoms, 2-chloro-1-fluoro-butane exhibits unique chemical properties, such as increased reactivity and polarity compared to its non-halogenated counterparts. It is primarily used as a chemical intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals. However, due to its potential environmental and health risks, proper handling and disposal protocols must be followed when working with 2-chloro-1-fluoro-butane.

686-63-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 686-63-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,8 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 686-63:
(5*6)+(4*8)+(3*6)+(2*6)+(1*3)=95
95 % 10 = 5
So 686-63-5 is a valid CAS Registry Number.

Free Radical Substitution. Part 37. The Effect of Solvent on the Atomic Chlorination of 1-Substituted Butanes and Related Compounds

Potter, Alan,Tedder, John M.

, p. 1689 - 1692 (2007/10/02)

Experimental results reported in this paper show that the relative selectivity of atomic chlorination of 1-substituted butanes and related compounds is greatly influenced by the phase and by solvents.Solvents can be divided into three classes: (a) inert, (b) solvents which decrease the selectivity, and (c) solvents which increase the selectivity.The second group solvate the transition state and the third group solvate the chlorine atoms.
