mesyln.

Brit.

/ˈmiːsʌɪl/,

/ˈmiːsɪl/, U.S.

/ˈmɛsəl/,

/ˈmisəl/

Origin: Formed within English, by compounding. Etymons: methane n., sulphonyl n.

Etymology: < me- (in methane n.) + -syl ( < s- and -yl in sulphonyl n.). Compare earlier tosyl n.

Chemistry.

More fully mesyl group. The methanesulphonyl radical, H₃CSO₂—. Usually attributive.
