CAS 227456-27-1 1-Pentanol,3-Mercapto-2-Methyl- Flavour Additives 99.4% Purit with Boxwood, broom, gooseberry flavor

Physical & Chemical Properties

• Appearance: Typically a colorless to pale yellow liquid.

• Odor: This is its most defining characteristic. At pure, high concentrations, it has a pungent, sulfurous, meaty, or broth-like smell. However, when highly diluted, it transforms into a sweet, savory, juicy, and tropical fruit aroma, often described as resembling grapefruit, passion fruit, or guava.

• Solubility: Slightly soluble in water due to the alcohol group, but more soluble in organic solvents (ethanol,  perfume oils).

• Reactivity: The thiol group makes it susceptible to oxidation, where it can form disulfides. It can also participate in reactions typical of both thiols and alcohols.

Primary Use: Aroma & Flavor Chemistry

3-Mercapto-2-methylpentan-1-ol is predominantly and almost exclusively used in the fragrance and flavor industry.

• In Perfumery: It is a powerful top-note ingredient. Perfumers use it in trace amounts (often in parts per million or billion) to add:

  • Tropical, fruity accents to floral, fruity, and fantasy fragrances.

  • A juicy, fresh "boost" to citrus colognes.

  • A modern, diffusive effect. Its aroma helps create a compelling first impression in a scent composition.

• In Flavoring: It is used to impart or enhance:

  • Tropical fruit flavors (especially grapefruit, passion fruit) in beverages, candies, and desserts.

  • Savory, meaty nuances in reaction flavors or savory applications (though less common than for fruit).
