40811-49-2 Usage
General Description
2-(Isopropylthio)ethanol is a chemical compound with the formula C5H12OS. It is a colorless liquid with a strong, unpleasant odor. This chemical is commonly used as a solvent and in the production of pesticides and other chemical compounds. It is also used in the manufacturing of rubber products and as a corrosion inhibitor in fuel systems. Additionally, 2-(Isopropylthio)ethanol is used in the formulation of personal care products and as a stabilizer in the cosmetic industry. However, it is important to handle this chemical with care, as it can be irritating to the skin, eyes, and respiratory system.
Check Digit Verification of cas no
The CAS Registry Mumber 40811-49-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,8,1 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 40811-49:
(7*4)+(6*0)+(5*8)+(4*1)+(3*1)+(2*4)+(1*9)=92
92 % 10 = 2
So 40811-49-2 is a valid CAS Registry Number.

Unexpected steric effects of "remote" alkyl groups on the rate of conjugate additions to alkyl α,β-ethylenic sulfones, sulfoxides, and esters

Examination of conjugated ethylenic sulfones, sulfoxides, and esters in Michael-type addition reactions reveals, for the first time, that the size of the heteroatom-attached alkyl group affects the rate of conjugate addition. Molecular modeling strongly suggests that what are generally considered to be "remote" alkyl groups in -CβH=CαHS(O) n,-alkyl systems and -CH2CβH=C αHCOO-alkyl systems are actually not remote from the β-carbon atom of the Michael accepting unit. Molecular modeling clearly shows that the alkyl groups in these Michael acceptors shield the β-carbons in the following order: Et i-Pr > t-Bu.
