2-Thiazolyl compounds

2-Aminothiazole is a heterocyclic amine featuring a thiazole core. It can also be considered a cyclic isothiourea. It possesses an odor similar to pyridine and is soluble in water, alcohols and diethyl ether. 2-Aminothiazole itself is mainly of academic interest, with few exceptions. It is a precursor to a sulfathiazole ("sulfa drugs"). 2-Aminothiazole can be used as a thyroid inhibitor in the treatment of hyperthyroidism.

Sulfathiazole is an organosulfur compound used as a short-acting sulfa drug. Formerly, it was a common oral and topical antimicrobial, until less toxic alternatives were discovered.

Phthalylsulfathiazole (also known as sulfathalidine) is a sulfonamide broad-spectrum antimicrobial used primarily for treating gastrointestinal infections.

Succinylsulfathiazole (also known as sulfasuxidine) is a sulfonamide. It is also spelled as succinylsulphathiazole. It is a white or yellow-white crystalline powder. It dissolves in aqueous solutions of alkali hydroxides and carbonates but is very slightly soluble in water.
