Butane, 3-chloro-1-fluoro-, also known as 1-fluoro-3-chlorobutane or 3-chloro-1-fluorobutane, is a halogenated alkane with the chemical formula C4H8ClF. It is a colorless, volatile liquid with a molecular weight of 108.56 g/mol. Butane, 3-chloro-1-fluoro- is a derivative of butane, where one hydrogen atom is replaced by a chlorine atom at the third carbon position and a fluorine atom at the first carbon position. Due to its halogenated nature, it exhibits properties such as increased reactivity and polarity compared to its parent hydrocarbon. It is primarily used as a chemical intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals. However, it is important to handle Butane, 3-chloro-1-fluoro- with care, as it may pose health risks and environmental concerns due to its potential toxicity and persistence in the environment.

691-40-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 691-40-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,9 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 691-40:
(5*6)+(4*9)+(3*1)+(2*4)+(1*0)=77
77 % 10 = 7
So 691-40-7 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.
