Chemical Properties

white to light yellow crystal powde

Uses

This study developed a series of novel 2-amino-4-methylthiazole analogues for combating Gram-positive bacterial, Gram-negative bacterial, and fungal infections[1]. 2-Amino-4-methylthiazole serves as a corrosion inhibitor for electrogalvanized steel in 0.1 M neutral NaCl solution[2].
