39199-37-6 Usage
General Description
1-(2-chloroethyl)-2-methylbenzene, also known as o-chloroethyltoluene or 2-methyl-1-(2-chloroethyl)benzene, is an organic compound with the chemical formula C9H11Cl. It is a colorless to pale yellow liquid with a strong, aromatic odor. 1-(2-chloroethyl)-2-methylbenzene is primarily used as an intermediate in the production of pharmaceuticals, dyes, and other organic synthesis. It is also used as a solvent and as a reactive intermediate in chemical synthesis. The presence of a chloroethyl group makes this compound reactive and potentially hazardous, with known toxic and irritant effects on the skin, eyes, and respiratory system. Therefore, it is important to handle and use this chemical with proper precautions and in accordance with safety guidelines.
Check Digit Verification of cas no
The CAS Registry Mumber 39199-37-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,1,9 and 9 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 39199-37:
(7*3)+(6*9)+(5*1)+(4*9)+(3*9)+(2*3)+(1*7)=156
156 % 10 = 6
So 39199-37-6 is a valid CAS Registry Number.

A stereoselective hydroxylation and enantioselective dehalogenation cascade reaction was developed for the synthesis of optically active β-haloalcohols from halohydrocarbons. This cascade system employed P450 and halohydrin dehalogenase as two compatible biocatalysts, allowing a straightforward, greener and efficient access to β-halohydrins with excellent enantioselectivities (98-99%).
