Description

(-)-Camphor CAS NO 464-48-2 is the naturally occurring levorotatory enantiomer of the bicyclic terpenoid ketone, known for its distinct aromatic odor and crystalline form. This high-purity chiral building block is essential for applications requiring specific stereochemistry, offering superior performance over racemic mixtures. It is a critical intermediate for the pharmaceutical, fragrance, and fine chemical industries, where its defined stereochemistry is vital for producing active ingredients and high-value aroma chemicals.

Application

• Pharmaceutical Synthesis: A key chiral intermediate in the production of active pharmaceutical ingredients (APIs), particularly for drugs targeting the central nervous system and as a starting material for camphor-derived therapeutics.
• Fragrance & Flavor Industry: Used as a base note and fixative in premium perfumery and for imparting its characteristic fresh, penetrating aroma in cosmetic and personal care formulations.
• Fine Chemical Manufacturing: Serves as a versatile chiral synthon in asymmetric synthesis for creating complex organic molecules in agrochemicals and specialty chemicals.
• Research & Development: Employed as a standard or reagent in analytical chemistry and biochemical research due to its well-defined stereochemical properties.
• Traditional & Modern Therapeutics: Used in topical analgesics, anti-pruritics, and decongestant preparations, leveraging its cooling and mild anesthetic properties.
• Polymer & Plasticizer Modifier: Acts as a plasticizer for cellulose esters and nitrocellulose, and as a component in specialty polymer formulations.
