3-Methyl-2,5-dihydrofuran is an organic compound with the molecular formula C5H8O. It is a colorless liquid with a strong, pungent odor. This heterocyclic compound features a furan ring, which is a five-membered ring containing four carbon atoms and one oxygen atom. The 3-methyl group is attached to the third carbon atom of the furan ring, and the compound is classified as a dihydrofuran due to the presence of two hydrogen atoms attached to the ring, reducing the degree of unsaturation. 3-Methyl-2,5-dihydrofuran is used as a synthetic intermediate in the production of various chemicals, pharmaceuticals, and fragrances. It is also known for its potential applications in the synthesis of biofuels and as a solvent in various industrial processes.

1708-31-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1708-31-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,0 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1708-31:
(6*1)+(5*7)+(4*0)+(3*8)+(2*3)+(1*1)=72
72 % 10 = 2
So 1708-31-2 is a valid CAS Registry Number.

Isomerization of epoxyalkenes to 2,5-dihydrofurans

-

Example 330, (2008/06/13)

Disclosed are processes for the isomerization of epoxyalkenes to dihydrofurans by contacting an epoxyalkene with a catalyst comprising a quaternary organic onium iodide compounds, optionally deposited on a non-acidic support and/or in combination with a Lewis acid co-catalyst. The catalyst may comprise a supported catalyst, an unsupported catalyst or a solution of the catalytically-active components in an inert, organic solvent.
