2-Butenoic acid, 3-chloro-, methyl ester is an organic compound with the chemical formula C5H7ClO2. It is a derivative of 2-butenoic acid, featuring a chlorine atom at the third carbon position and a methyl ester group attached to the carboxylic acid functionality. This colorless liquid is soluble in organic solvents and has a molecular weight of 136.55 g/mol. It is synthesized by esterification of 3-chloro-2-butenoic acid with methanol and is used in the production of pharmaceuticals, agrochemicals, and other chemical intermediates. Due to its reactivity, it is important to handle 2-Butenoic acid, 3-chloro-, methyl ester with care, following proper safety protocols.

7166-18-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7166-18-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,6 and 6 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7166-18:
(6*7)+(5*1)+(4*6)+(3*6)+(2*1)+(1*8)=99
99 % 10 = 9
So 7166-18-9 is a valid CAS Registry Number.

Synthesis of functionalized 2-alkoxybenzoates, 2-aryloxybenzoates and xanthones based on formal [3+3] cyclocondensations of 3-alkoxy- and 3-aryloxy-1-silyloxy-1,3-butadienes with 3-silyloxy-2-en-1-ones

Functionalized 2-alkoxy- and 2-aryloxybenzoates were prepared by formal [3+3] cyclocondensations of 3-alkoxy- and 3-aryloxy-1-silyloxy-1,3-butadienes with 3-silyloxy-2-en-1-ones. The reaction of 2-aryloxybenzoates with concentrated sulfuric acid resulted in the formation of xanthones.
