3188-00-9 Usage

Description

2-Methyltetrahydrofuran-3-one has a bread, buttery topnote. May be prepared by hydrolytic decarboxylation of 2-methyl-4-carbomethoxytetrahydrofuran- 3-one; by acid-catalyzed ring closure of p-alkoxy- diazoketones.

Chemical Properties

Different sources of media describe the Chemical Properties of 3188-00-9 differently. You can refer to the following data:
1. 2-Methyltetrahydrofuran-3-one has an odor reminiscent of wintergreen.
2. Colorless to light yellow liqui

Occurrence

Reported found as a constituent in coffee aroma; also as a volatile flavor component in roasted filbert nuts. Also reported found in guava, raisin, pineapple, onion, baked and fried potato, tomato, wheat bread, crispbread, smoked fish, cooked beef and pork, pork liver, rum, cocoa, coffee, peanuts, potato chips, passion fruit, beans, mushroom, tamarind, sweet potato, licorice, malt, dried bonito, cherimoya, okra and maté

Uses

2-Methyltetrahydro-3-furanone has been employed as an quorum sensing inhibitor-molecule to investigate its effect on growth and biofilm formation in Hafnia alvei.

By hydrolytic decarboxylation of 2-methyl-4-carbomethoxytetrahydrofuran-3-one; by acid-catalyzed ring closure of β-alkoxy-diazoketones

Taste threshold values

Taste characteristics at 75 ppm: nutty and astringent with a slight creamy, almond nuance.

Check Digit Verification of cas no

The CAS Registry Mumber 3188-00-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,8 and 8 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3188-00:
(6*3)+(5*1)+(4*8)+(3*8)+(2*0)+(1*0)=79
79 % 10 = 9
So 3188-00-9 is a valid CAS Registry Number.

A short and efficient synthesis of 2-methyltetrahydrofuran-3-one

Ragoussis, Valentine,Lagouvardos, Dimitrios J.,Ragoussis, Nikitas

, p. 4273 - 4278 (1998)

2-Methyltetrahydrofuran-3-one (3), a volatile constituent of the aroma complex of roasted coffee, is efficiently prepared in satisfactory yield (55,2%) by oxidative hydroxylation of the 2-acetylbutyrolactone (4).

Thermal decomposition of ascorbic acid

Vernin, Gaston,Chakib, Soundouss,Rogacheva, Sonia M.,Obretenov, Tzvetan D.,Parkanyi, Cyril

, p. 1 - 15 (2007/10/03)

Thermal degradation of L-ascorbic acid at 300 °C in the absence of a solvent yielded mostly furan derivatives and α,β-unsaturated cyclic ketones with a five-membered ring. Some of the furan derivatives are the same as those obtained in the Maillard reaction, with the reductones undergoing retroaldol reaction, decarboxylation, oxidation, and hydrolysis. In propylene glycol, under milder conditions (180 °C), the carbonyl and dicarbonyl derivatives resulting from the decomposition react with the solvent and give cyclic acetals and ketals (1,3-dioxolanes). The products were identified by GC-MS using the SPECMA data bank.

Tarnchompoo, Bonkoch,Thebtaranonth, Yodhathai

, p. 5567 - 5570 (2007/10/02)

A straight forward synthesis of dihydro-3(2H)-furanone is described.An attempted preparation of the oxetan-3-one precursor 10 by this method gave, instead, the ring enlargement product 11.
