7209-04-3

Butanedioic acid, chloro-, diethyl ester, also known as chlorosuccinic acid diethyl ester, is an organic compound with the chemical formula C6H11ClO4. It is a colorless liquid that is soluble in most organic solvents. This ester is derived from butanedioic acid (succinic acid) and is characterized by the presence of a chloro group. It is primarily used as a chemical intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals. Due to its reactivity, it is important to handle chlorosuccinic acid diethyl ester with care, as it can be harmful if inhaled, ingested, or absorbed through the skin.

7209-04-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7209-04-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,0 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7209-04:
(6*7)+(5*2)+(4*0)+(3*9)+(2*0)+(1*4)=83
83 % 10 = 3
So 7209-04-3 is a valid CAS Registry Number.

Application of Low Energy CID in the Determination of Structures of + Ions Obtained From Diethyl Halosuccinates Under Electron Impact

Weisz, A.,Mandelbaum, A.,Blum, W.,Domon, B.,Muller, D,et. al.

, p. 61 - 63 (2007/10/02)

Low energy collision induced dissociation (CID) spectra indicate that m/z 173 ions formed by the loss of a halogen atom from diethyl chloro- and bromo-succinate under electron impact are mixtures of O-protonated diethyl maleate (>90percent) and fumarate (+ ion obtained from diethyl iodosuccinate shows that only a small fraction of the + ions are the O-protonated species formed by hydrogen migration.The result of this study demonstrate the potential of low energy CID in the determination of structure (including configuration) of gas phase ions.
