2-[(2,4,6-trichlorophenoxy)methyl]oxirane, also known as 2,4,6-trichlorophenyl glycidyl ether, is a chemical compound with the molecular formula C9H7Cl3O2. It is a colorless to pale yellow liquid with a molecular weight of 265.51 g/mol. 2-[(2,4,6-trichlorophenoxy)methyl]oxirane is an epoxide derivative, characterized by the presence of a three-membered oxirane ring and a 2,4,6-trichlorophenoxy group attached to the 2-position of the oxirane. It is used as an intermediate in the synthesis of various agrochemicals, particularly herbicides. Due to its potential toxicity and environmental concerns, it is important to handle 2-[(2,4,6-trichlorophenoxy)methyl]oxirane with care and in accordance with proper safety protocols.

3331-21-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3331-21-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,3 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3331-21:
(6*3)+(5*3)+(4*3)+(3*1)+(2*2)+(1*1)=53
53 % 10 = 3
So 3331-21-3 is a valid CAS Registry Number.

A NEW APPLICATION OF CORRELATION EQUATIONS. INFLUENCE OF SUBSTITUENT ON BASICITY OF A SERIES OF CHLOROPHENYL GLYCIDYL ETHERS

Stolarzewicz, Andrzej,Dworak, Andrzej,Jedlinski, Zbigniew

, p. 2517 - 2523 (2007/10/02)

The relation between the basicity of simple oxiranes and substituent constants was described earlier by the common equation pKb=co+c1?.It has been shown that this equation is not satisfied in the case of chlorophenyl glycidyl ethers, when the pKa values of chlorophenols have been taken as a measure of the inductive effect of chlorophenoxy substituent and pKb have been estimated from infrared measurements.The modification of the equation to the following form: pKb=co+(c1+c2Sk)pKa by considerarion of the conformation factor Sk make a good correlation possible.The possibility of the existence of some chlorophenyl glycidyl ethers rotameres has been also discussed on the above basis.
