CAS 1003-61-8: 2-Amino-5-thiazolecarboxaldehyde

2-Amino-1,3-thiazole-5-carboxaldehyde

2-Amino-5-formylthiazole is a dyebath that is used as an electron acceptor in dyeing. It is also a formyl donor and can be used to suppress the formation of nitro groups. 2-Amino-5-formylthiazole has been shown to have antibacterial activity against Gram-positive bacteria. The methylene group on this dyebath reacts with the halogens, which results in the release of acid and the formation of a new carbon-halogen bond. This reaction is reversible, which provides an opportunity for the recovery of 2-amino-5-formylthiazole from waste water streams.

Applications 2-Amino-5-formylthiazole is a useful reagent for the preparation of cationic azo dyes. References Salvador, M. A., et al.: Dyes and Pigments, 82, 118 (2009); Salvador, M. A., et al.: Tetrahedron, 64, 299 (2008)
