Description

(R)-(+)-δ-Decanolactone CAS NO 2825-91-4 is a high-purity, optically active lactone compound valued for its distinct flavor and fragrance profile. This chiral intermediate is essential for synthesizing fine chemicals and active pharmaceutical ingredients (APIs) where stereochemistry is critical. It is primarily sought after by manufacturers in the flavor & fragrance, pharmaceutical, and specialty chemical industries for creating premium products.

Application

• Flavor and Fragrance Ingredient: Used as a key chiral building block for creating natural-tasting peach, coconut, and dairy flavor notes, as well as complex fragrance compounds.
• Pharmaceutical Intermediate: Serves as a critical chiral synthon in the asymmetric synthesis of various APIs and bioactive molecules.
• Specialty Chemical Synthesis: Employed in the production of advanced polymers, liquid crystals, and other performance materials requiring specific stereochemistry.
• Agrochemical Research: Acts as a precursor for developing novel, stereospecific pesticides and plant growth regulators.
• Food Additive Production: Utilized in the manufacture of flavoring agents and food additives where the (R)-enantiomer is required for authenticity.
