5-(2-hydroxyethyl)-4-methylthiazole is a 1,3-thiazole that is thiazole substituted by a methyl group at position 4 and a 2-hydroxyethyl group at position 5.
Definition
5-(2-hydroxyethyl)-4-methylthiazole is a 1,3-thiazole that is thiazole substituted by a methyl group at position 4 and a 2-hydroxyethyl group at position 5. It has a role as a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a human metabolite. It is a primary alcohol and a member of 1,3-thiazoles. It is functionally related to a 5-(2-hydroxyethyl)-1,3-thiazole. It derives from a hydride of a thiazole.
