Thiol vs. Sulfur

A thiol () or thiol derivative is any organosulfur compound of the form R−SH, where R represents an alkyl or other organic substituent. The –SH functional group itself is referred to as either a thiol group or a sulfhydryl group, or a sulfanyl group.

Sulfur (in British English: sulphur) is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent and nonmetallic.

an organic compound containing the group —SH, i.e. a sulphur-containing analogue of an alcohol.

Symbol S A pale yellow nonmetallic element occurring widely in nature in several free, allotropic and crystal forms and combined in numerous sulfates and sulfides. It is used in black gunpowder, rubber vulcanization, the manufacture of insecticides and pharmaceuticals, and in the preparation of sulfur compounds such as hydrogen sulfide and sulfuric acid. Atomic number 16; atomic weight 32.066; melting point 115.21°C; boiling point 444.61°C; specific gravity at 20°C (rhombic) 2.07, (monoclinic) 2.00; valence 2, 4, 6. See Periodic Table.

A sulfur-containing organic compound with the general formula RSH where R is any hydrocarbon group. Also called mercaptan.

Any of various butterflies of the subfamily Coliadinae of the family Pieridae, having yellow or orange wings often marked with black.

(organic chemistry) A univalent organic radical (-SH) containing a sulphur and a hydrogen atom; a compound containing such a radical.

To treat with sulfur or a compound of sulfur.

(uncountable) A chemical element (symbol S) with an atomic number of 16.

A yellowish green colour, like that of sulfur.

Any of various pierid butterflies of the subfamily Coliadinae, especially the sulfur-coloured species.

Of a yellowish green colour, like that of sulfur.

(transitive) To treat with sulfur, or a sulfur compound, especially to preserve or to counter agricultural pests.

an abundant tasteless odorless multivalent nonmetallic element; best known in yellow crystals; occurs in many sulphide and sulphate minerals and even in native form (especially in volcanic regions)
