Butane, 3-chloro-1,1,1-trifluoro-3-methyl-, also known as 1,1,1-trifluoro-3-chloro-3-methylbutane, is a halogenated hydrocarbon with the chemical formula C5H9ClF3. This colorless liquid is a derivative of butane, featuring a chlorine atom at the third carbon position, three fluorine atoms at the first carbon position, and a methyl group at the third carbon position. It is an important intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals due to its unique combination of functional groups. The compound is typically produced through chemical reactions involving fluorination and chlorination processes. It is also known for its low boiling point, high reactivity, and potential use as a refrigerant or propellant in certain applications. However, due to its environmental and health concerns, especially its potential to contribute to ozone depletion, its use is regulated or restricted in many countries.
The CAS Registry Mumber 352-46-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,5 and 2 respectively; the second part has 2 digits, 4 and 6 respectively. Calculate Digit Verification of CAS Registry Number 352-46: (5*3)+(4*5)+(3*2)+(2*4)+(1*6)=55 55 % 10 = 5 So 352-46-5 is a valid CAS Registry Number.
