406-41-7 Usage
General Description
1,1,1-Trifluoro-2-butyne, also known as trifluoro-sec-butyl acetylene, is a chemical compound with the molecular formula C4H5F3. It is a colorless, flammable gas with a faint odor and is highly reactive. It is commonly used as a building block in the synthesis of various pharmaceuticals, agrochemicals, and specialty chemicals. Its unique chemical structure and properties make it useful in organic synthesis, as well as in the production of fluorinated compounds. However, it should be handled with caution as it is highly flammable and can cause skin and eye irritation upon contact. Additionally, it is considered harmful if inhaled and should be used in a well-ventilated area with proper protective equipment.
Check Digit Verification of cas no
The CAS Registry Mumber 406-41-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,0 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 406-41:
(5*4)+(4*0)+(3*6)+(2*4)+(1*1)=47
47 % 10 = 7
So 406-41-7 is a valid CAS Registry Number.

Method for producing 4,4,4- Trifluorobutane-2-One
-
Page/Page column 6-7, (2009/09/26)
The present invention provides a novel method for preparing 4,4,4-trifluorobutane-2-one by providing a fluorobutene selected from the group consisting of 2,4,4,4-tetrafluoro-1-butene, (E)-1,1,1,3-tetrafluoro-2-butene, (Z)-1,1,1,3-tetrafluoro-2-butene, and mixture thereof; and reacting the fluorobutene(s) with a proton acid and water.
