Ethenesulfonic acid potassium salt, also known as potassium vinylsulfonate or potassium 2-propen-1-ylsulfonate, is a chemical compound with the molecular formula C3H5KO3S. It is a colorless to pale yellow crystalline solid that is soluble in water. This potassium salt is derived from the sulfonation of ethene (ethylene), a process that introduces a sulfonic acid group to the molecule. It is used as a chemical intermediate in the synthesis of various organic compounds, including dyes, pharmaceuticals, and other specialty chemicals. The compound is also known for its use in the preparation of cationic surfactants and as a stabilizer in the polymer industry. Due to its reactivity, it is important to handle it with care, following proper safety protocols.

7308-65-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7308-65-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,0 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7308-65:
(6*7)+(5*3)+(4*0)+(3*8)+(2*6)+(1*5)=98
98 % 10 = 8
So 7308-65-8 is a valid CAS Registry Number.

A domino approach (hydrolysis/dehydrohalogenation/heck coupling) for the synthesis of styrene sulfonate salts

Prakash, G. K. Surya,Jog, Parag V.,Krishnan, Hema S.,Olah, George A.

, p. 2140 - 2143 (2011)

A domino approach of hydrolysis/dehydrohalogenation/Heck coupling was used to synthesize styrene sulfonate salts from iodoarenes and chloroethanesulfonyl chloride in good to excellent yields. Methodology was applicable for heterocyclic as well as disubstituted iodoarenes. Some of the key features of this synthetic methodology include the use of phosphine free catalytic system, water as an environmentally friendly solvent, short reaction times, and absence of additives.
