Origin: Formed within English, by derivation. Etymons: mercaptan n., -ide suffix.

Etymology: < mercapt- (in mercaptan n.) + -ide suffix.

Chemistry.

A salt of a thiol (mercaptan), containing the anion RS⁻.

1835 Rec. Gen. Sci. 1 110 Mercaptan when obtained pure from the mercaptide of mercury, is colourless, with a smell of assafœtida.

1836 W. T. Brande Man. Chem. (ed. 4) 1109 When mercaptan is acted on by potassium, hydrogen is evolved, and a mercapturet or mercaptide of potassium is formed.

1946 Thorpe's Dict. Appl. Chem. (ed. 4) VII. 559/2 Lead and mercury mercaptides of the type M(SR)₂ generally crystallise well from organic solvents.

1966 McGraw-Hill Encycl. Sci. & Technol. (rev. ed.) VIII. 227/2 The insoluble mercury salts (mercaptides) are used to isolate and identify mercaptans.

1992 Biochemistry 31 194/1 These estimates indicate significantly weaker coupling to axial nitrogen when the sixth ligand is mercaptide sulfur.
