General Description
1-CHLORO-4-IODO-2,5-DIMETHOXYBENZENE, also known as 1-chloro-4-iodo-2,5-dimethoxybenzene or 1-(4-chloro-2,5-dimethoxyphenyl)-4-iodobenzene, is a chemical compound with the molecular formula C8H8ClIO2. It is a derivative of benzene with chlorine and iodine atoms attached to different carbon positions and two methoxy groups attached to the benzene ring. 1-CHLORO-4-IODO-2,5-DIMETHOXYBENZENE is commonly used as an intermediate in the synthesis of pharmaceuticals and organic materials. It is also a building block for various heterocyclic compounds. 1-CHLORO-4-IODO-2,5-DIMETHOXYBENZENE is a white to off-white solid with a molecular weight of 310.51 g/mol and a melting point of 131-134°C. It is important to handle this chemical with care, following proper safety protocols, due to its potential for causing skin and eye irritation.
Check Digit Verification of cas no
The CAS Registry Mumber 90064-46-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,0,6 and 4 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 90064-46:
(7*9)+(6*0)+(5*0)+(4*6)+(3*4)+(2*4)+(1*6)=113
113 % 10 = 3
So 90064-46-3 is a valid CAS Registry Number.

A facile synthesis of 1,4-dialkoxy-2,5-diiodobenzenes: reaction of dialkoxybenzenes with iodine monochloride in alcoholic solvents

, p. 98 - 100 (2013/09/05)
A facile synthesis of 1,4-dialkoxy-2,5-diiodobenzenes via diiodination of the corresponding dialkoxybenzenes with iodine monochloride has been developed. Employment of ah alcoholic solvent as a reaction medium is crucial for attaining a high yield; the reaction in a nonalcoholic solvent usually resulted in a poor yield. The diiodobenzene derivatives are useful intermediates in the synthesis of such advanced materiais as soluble phenylenevinylene polymers anal dialkoxy derivatives of 7,7,8,8-tetracyanoquinodimethane.
