PRODUCT INTRODUCTION
description
2-isobutylthiazole is a 1,3-thiazole in which the hydrogen at position 2 has been replaced by an isobutyl group. A food flavour component with a green note that adds the characteristics of ripe tomatoes. Used in blackcurrent, papaya, melon, raspberry, and roast beef flavours, it also enhances the flavour of fresh lime. It has a role as a flavouring agent, a pheromone and a Maillard reaction product.
