/ˈmɛsəˌdin/

Origin: Formed within English, by derivation. Etymons: mesityl n., -idine suffix.

Etymology: < mes- (in mesityl n.) + -idine suffix. Slightly earlier attested in the compound nitromesidine n. at nitro- comb. form 3b. N.E.D. (1906) gives the pronunciation as (me·sidin) /ˈmɛsɪdɪn/.

Chemistry.

A colourless oily liquid obtainable by boiling nitromesitylene with tin and hydrochloric acid; 2,4,6-trimethylaniline, (CH₃)₃·C₆H₂·NH₂.

1866 W. Odling Lect. Animal Chem. 60 Certain highly complex bodies procurable from vinegar, such as mesidine C₉H₁₃N, and nitro-mesidine C₉H₁₂N₂O₂.

1910 Encycl. Brit. I. 857/2 Trimethyl phenyl ammonium iodide is converted into mesidine hydriodide.

1966 Science 18 Feb. 874/2 As the dose of mesidine was increased in rats the amount of DNA per gram of liver increased proportionately.

1993 Heteroatom Chem. 4 427/2 Mesidine (mesitylenamine) was allowed to react with fluorenone in the presence of boron trifluoride etherate.
