Description

(+)-Neomenthol CAS NO 2216-52-6 is a stereoisomer of menthol, a key monoterpenoid alcohol with a distinct, clean, and cooling mint-like odor. This high-purity isomer is essential for applications requiring specific stereochemical profiles, offering superior control over fragrance, flavor, and sensory characteristics. It is a critical intermediate and active ingredient for manufacturers in the flavor and fragrance, pharmaceutical, and personal care industries seeking to formulate premium products with precise sensory attributes.

Application

• Flavor & Fragrance Industry: A key component in creating sophisticated mint, peppermint, and cooling notes for perfumes, cosmetics, oral care products, and fine fragrances.
• Pharmaceutical Synthesis: Serves as a chiral building block and intermediate in the synthesis of active pharmaceutical ingredients (APIs) and medicinal compounds.
• Oral Care Products: Used in toothpastes, mouthwashes, and chewing gums to impart a fresh, cooling sensation and minty flavor.
• Tobacco Flavoring: Employed to enhance and modify the flavor profile of tobacco products.
• Topical Analgesics & Rubs: Utilized for its cooling and mild anesthetic properties in creams, balms, and liniments for muscle relief.
• Chemical Research & Development: Acts as a standard and reagent in stereochemical studies, organic synthesis, and analytical method development.
• Confectionery: Imparts a clean mint flavor in candies, breath mints, and other food-grade applications where specific isomer purity is required.
