Overview
Cyclohexenone is a cyclic unsaturated ketone with the molecular formula C6H8O. It serves as a crucial intermediate in organic synthesis due to its reactive α,β-unsaturated carbonyl structure. Industrially, it is produced through the oxidation of cyclohexene or dehydration of cyclohexanediols. Its versatility makes it valuable across multiple sectors, particularly in fine chemical manufacturing.
Physical and Chemical Properties
Cyclohexenone is a colorless to pale yellow liquid with a pungent odor. It has a density of 0.988 g/cm³ and boils at 168-170°C. The compound's solubility profile favors organic solvents like ethanol and ether. Chemically, the conjugated double bond and carbonyl group make it highly reactive in Michael additions, Diels-Alder reactions, and hydrogenation processes. These properties are exploited in synthesizing complex molecules.
Main Applications
In pharmaceuticals, cyclohexenone derivatives are building blocks for steroids and prostaglandins. Agrochemical manufacturers use it to produce pesticides and herbicides with enhanced efficacy. The fragrance industry employs cyclohexenone in musk and floral scent formulations. Additionally, it acts as a crosslinking agent in specialty polymer production for coatings and adhesives.
Safety and Storage
As a flammable liquid, cyclohexenone requires storage in approved containers away from ignition sources. Secondary containment is recommended to prevent spills. Personal protective equipment (gloves, goggles, respirators) is mandatory during handling due to its irritant properties. Facilities should maintain proper ventilation and have fire suppression systems in place.
B2B Procurement Guide
When sourcing cyclohexenone, prioritize suppliers with ISO 9001 certification and batch-specific COAs (Certificates of Analysis). Technical specifications should include purity (≥98%), water content (<0.5%), and peroxide levels. Bulk shipments typically use 200kg steel drums or IBC totes. Consider Just-in-Time delivery for this sensitive chemical to minimize storage risks. Negotiate MOQs based on projected usage to optimize costs.
