Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Journal of the Chemical Society, Perkin Transactions 1: Organic and Bio-Organic Chemistry (1972-1999) called An infrared study of rotational isomerism in thiazole-2-carboxylates, Author is Kaye, Perry T.; Meakins, G. Denis; Willbe, Charles; Williams, Peter R., which mentions a compound: 79247-77-1, SMILESS is NC1=NC(C)=C(Br)S1.[H]Br, Molecular C4H6Br2N2S, COA of Formula: C4H6Br2N2S.

Twenty-five alkyl thiazole-2-carboxylates with a range of 4- and 5-substituents were prepared through the Hantzsch synthesis. E.g., cyclocondensation reaction of (H2N)2CS with MeCOCH2Br followed by bromination, oxidation, and alkylation gave the thiazole esters I (R = Me, Et). Solutions of these esters show well resolved doublets in the carbonyl IR spectra, due to rotational isomers. The higher wave number components were assigned to the more polar carbonyl O,S-anti-s-trans rotamers and those at lower wave number to the O,S-syn-s-trans forms. Small, but systematic, differences between the Me esters were noted.
