2,3-Butanedithiol Chemical Properties,Usage,Production
Chemical Properties
Light yellow transparent liquid. It is meaty, coffee, and garlicky. Boiling point 69~70℃(3732Pa). Insoluble in water, miscible in oil.
Uses
2,3-Butanedithiol is a food spice used in roast beef, salami, coffee and more.
Definition
ChEBI: 2,3-Butanedithiol is an alkanethiol.
Structure and conformation
The conformational landscape of 2,3-butanedithiol may be rationalized as the 2,3-diol analogue. Briefly, the two tetrahedral stereogenic centers at the central (2,3) carbons produce two pairs of homochiral (R,R and S,S) and heterochiral (R,S and S,R) or meso stereoisomers, which, unlike in other techniques, can be easily distinguished by their rotational spectrum[1].
