pyridyln.

Brit.

/ˈpɪrᵻdʌɪl/,

/ˈpɪrᵻdɪl/, U.S.

/ˈpɪrəd(ə)l/

Origin: Formed within English, by derivation. Etymons: pyridine n., -yl suffix.

Etymology: < pyrid- (in pyridine n.) + -yl suffix. Compare German Pyridylchinolin (1886 or earlier; compare quot. 1887), Pyridyl (1890 or earlier).

Chemistry.

Each of three isomeric radicals derived from pyridine by the removal of a hydrogen atom. Usually attributive or as a formative element in chemical names.Formula: —C₅H₄N.

1887 Jrnl. Chem. Soc. 52 64 The silver salt, when heated, yields a pyridylquinoline, C₁₄N₂H₁₀.

1894 G. M'Gowan tr. A. Bernthsen Text-bk. Org. Chem. (ed. 2) xxxiii. 529 It [sc. nicotine] appears to be a pyridyl-n-methyl-pyrrolidine.

1935 Proc. Royal Soc. B. 118 424 Fluoride interferes seriously with many methods for determining iron... The rate of colour development with the pyridyl reagents is markedly affected.

1995 Biochemistry 34 768/2 The pyridyl group attached to the 6-position of the purine ring is very susceptible to nucleophilic displacement.
