10-Undecenal (CAS 112-45-8), also known as Undecylenic Aldehyde, is a high-value aromatic aldehyde and a critical derivative of castor oil. Characterized by its powerful, fatty-citrus odor with a distinct waxy-floral undertone, Hendecenal is a cornerstone of the fine fragrance industry, particularly in "aldehydic" perfume formulations. Beyond its sensory appeal, Undecylenic aldehyde is a highly reactive building block in organic synthesis, featuring a terminal double bond and an aldehyde group. This bifunctionality makes it an essential intermediate in the pharmaceutical & agrochemical sectors for creating antifungal agents and specialised pheromones. In Elemental Derivatives, context it represents the "Oxygenated Lipid" path, bridging renewable natural oils with advanced chemical manufacturing. We are a globally established 10-Undecenal supplier and various other aroma chemical manufacturer worldwide through comprehensive regulatory documentation (CoA), traceability, and consistent global supply capabilities, ensuring reliable lead times and quality assurance across all grades.

Key ingredient in "Aldehydic" perfumes (similar to the classic Chanel No. 5 profile) for "lift," "brilliance," and a clean, laundry-fresh top note
Soaps and detergents for its stability and ability to mask base odors (Long-lasting citrus-floral scent)
Synthesize derivatives related to Undecylenic Acid, which is a potent antifungal agent used in topical treatments for athlete’s foot and ringworm
Terminal alkene allows for "Click Chemistry" and cross-metathesis to link bioactive molecules
Vital precursor in the synthesis of lepidopteran pheromones. The 11-carbon chain is a common structural motif in the natural signaling chemicals of agricultural pests
Store in a cool (2-8°C preferred for longevity), dark place. Light and air sensitive.
Highly susceptible to oxidation-Converts to Undecylenic Acid if exposed to air. Often stabilized with BHT (100-500 ppm)
Nitrogen capping of drums is mandatory after opening to preserve the olfactory profile and purity
