thiazole. (n.d.). Retrieved October 23rd, 2018, from https://www.yourdictionary.com/thiazole
Any of a class of organic compounds containing a ring that consists of three carbon atoms, one nitrogen atom, and one sulfur atom. Thiamine, penicillin and its derivatives, various other drugs, and numerous dyes are thiazoles.
A colorless or pale yellow liquid used in making dyes and fungicides. Chemical formula:C3H3NS.
Thus benzene, (CH) gives thiophene, (CH) S, from which it is difficultly distinguished; pyridine, (CH) N, gives thiazole, (CH) N S, which is a very similar substance; naphthalene gives thionaphthen, C 11 S, with which it shows great analogies, especially in the derivatives.
Thiophene yields a similar series: isothiazole (only known as the condensed ring, isobenzothiazole), thiazole, diazosulphides, piazthioles, azosulphimes and thiobiazole (the formulae are easily derived from the preceding series by replacing oxygen by sulphur).
