2-Isobutylthiazole (18640-74-9) (C7H11NS)

2-Isobutylthiazole is a heterocyclic sulfur-containing compound known for its strong green, tomato-leaf, and slightly earthy odor. It appears as a colorless to pale yellow liquid and is insoluble in water but soluble in organic solvents such as alcohol and oils. It has high odor potency, low threshold value, and good stability under normal conditions, making it highly effective in trace amounts.

In terms of properties, it provides intense green and vegetal notes, excellent diffusion, and strong impact even at very low concentrations. It blends well with fruity, herbal, and floral ingredients, enhancing natural freshness in formulations.

Regarding uses and applications, 2-Isobutylthiazole is widely used in the flavor and fragrance industry. In flavors, it is used in very small quantities to impart tomato, green vegetable, and leafy notes in food products. In perfumery, it is used to create fresh, green accords in perfumes and personal care products such as soaps and shampoos.
