The material can be prepared by a Ritter reaction using N,2,3-trimethyl-2- isopropylbutyronitrile as the starting material and alkylating agents such as, for example, borates, carbonates, or phosphates.

Chemical Properties

2-Isopropyl-N-2,3-trimethylbutyramide has a cool, mint–menthol-type odor

Uses

Physiological coolant in foods, beverages, tobacco products, toiletries, cosmetics and pharmaceuticals.

Aroma threshold values

Aroma characteristics at 5.0%: slight cooling impact with little character.

Taste threshold values

Taste characteristics at 20 ppm: high-impacting cooling that lasts on the tongue and palate.

Trade name
