Description

(5E,9E)-6,10,14-Trimethylpentadeca-5,9,13-Trien-2-One is a high-purity, unsaturated ketone widely recognized for its role as a key intermediate in the synthesis of complex organic molecules. Its value lies in its specific conjugated triene structure, which is crucial for constructing isoprenoid chains found in vitamins, fragrances, and pharmaceuticals. This compound is essential for R&D chemists and production units in the flavor & fragrance, pharmaceutical, and fine chemical industries seeking reliable building blocks for terpene-based synthesis.

Application

• Flavor and Fragrance Intermediate: A critical precursor in the synthesis of terpenoid aroma chemicals and musk-like compounds.
• Pharmaceutical Synthesis: Serves as a key building block for the production of vitamins (e.g., Vitamin A, Vitamin K analogs) and other isoprenoid-derived active pharmaceutical ingredients (APIs).
• Fine Chemical Manufacturing: Used in the multi-step synthesis of complex natural products, agrochemicals, and specialty polymers.
• Research & Development: A valuable standard and starting material in organic chemistry research, particularly in studies involving polyene cyclizations and carbonyl chemistry.
• Cosmetic Ingredients: Employed in the synthesis of certain UV absorbers and skin-conditioning agents with terpene backbones.
