1120-59-8 Usage

General Description

2,3-Dihydrothiophene is a heterocyclic organic compound with the molecular formula C4H6S. It is a cyclic sulfide, containing a five-membered ring with four carbon atoms and one sulfur atom. As a volatile liquid with a strong, unpleasant odor, it is commonly used as a building block in the synthesis of pharmaceuticals, agrochemicals, and other organic compounds. 2,3-Dihydrothiophene is also a useful intermediate in the production of polymers, dyes, and organic materials. Due to its high reactivity and potential health hazards, it should be handled and stored with caution in a well-ventilated area.

Check Digit Verification of cas no

The CAS Registry Mumber 1120-59-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,2 and 0 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1120-59:
(6*1)+(5*1)+(4*2)+(3*0)+(2*5)+(1*9)=38
38 % 10 = 8
So 1120-59-8 is a valid CAS Registry Number.

Onion essential oil chemistry. Cis-and trans-2-mercapto-3,4-dimethyl 2,3-Dihydrothiophene (cas 1120-59-8) from pyrolysis of bis(1-propenyl) disulfide☆09/29/2019

Heating the onion oil component bis(1-propenyl) disulfide gives cis/-and trans-2-mercapto-3,4-dimethyl-2,3-dihydrothiophene which can lose H2S upon further heating giving 3,4-dimethylthiophene. A dithio-Claisen rearrangement is proposed for the key step.detailed

RuO2 clusters within LTA zeolite cages: Consequences of encapsulation on catalytic reactivity and selectivity

Zhan, Bi-Zeng,Iglesia, Enrique

, p. 3697 - 3700 (2008/03/11)

(Figure Presented) Trapped! The title system (ca. 1 nm diameter; left) catalyzes methanol oxidation with higher turnover rates than clusters on SiO2 supports. Spatial constraints lead to the preferential oxidation of methanol over larger alcohols. Restricted access to active sites also protects encapsulated Ru clusters (right) against inhibition of ethene hydrogenation by organosulfur compounds.
