methyl

Relating to or being the simplest hydrocarbon unit, CH₃, that can occur as a substituent in an organic compound or as an ion or radical.

The hypothetical radical (CH₃) of woodspirit and its derivatives. It is analogous to ethyl in its chemical relations.

A univalent hydrocarbon radical, CH3-, not existing alone but regarded as an essential residue of methane, and appearing as a component part of many derivatives

a light, volatile, inflammable liquid, CH3.OH, obtained by the distillation of wood, and hence called wood alcohol or wood spirit; tecnically referred to as methanol; — called also methol, carbinol, etc.

a colorless, inflammable, alkaline gas, CH3.NH2, having an ammoniacal, fishy odor. It is produced artificially, and also occurs naturally in herring brine and other fishy products. It is regarded as ammonia in which a third of its hydrogen is replaced by methyl, and is a type of the class of substituted ammonias.

a light, volatile ether CH3.O.CH3, obtained by the etherification of methyl alcohol; — called also methyl oxide or dimethyl ether.

an artificial dye, consisting of certain methyl halogen derivatives of rosaniline.

The univalent hydrocarbon radical, CH3, formally derived from methane by the loss of a hydrogen atom.
