199866-90-5 Usage

Uses

1,4-Difluoro-2,5-dimethoxybenzene is suitable reagent used in a study to investigate the direct anodic electrodeposition of polypyrrole, poly(3,4-ethylenedioxythiophene) and polythiophene on Cu electrodes by employing a corrosion inhibitor. It may be used in the following studies:Synthesis of 7-fluoro-5,8-dimethoxy-1-naphthol. As novel precursor for the iterative double benzyne-furan Diels-Alder reactions.Synthesis of 1,4-bis(phosphino)-2,5-difluoro-3,6-dimethoxybenzenes.

General Description

1,4-Difluoro-2,5-dimethoxybenzene is an alkoxy arene. It undergoes 1:3 reaction with TaF5 in chloroform at 40-50°C to afford long-lived radical cation salts [1,4-F2-2,5-(MeO)2C6H2][Ta2F11].

Check Digit Verification of cas no

The CAS Registry Mumber 199866-90-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,8,6 and 6 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 199866-90:
(8*1)+(7*9)+(6*9)+(5*8)+(4*6)+(3*6)+(2*9)+(1*0)=225
225 % 10 = 5
So 199866-90-5 is a valid CAS Registry Number.
