1-Octanal
Overview
1-Octanal is a straight-chain aliphatic aldehyde with eight carbon atoms. It is naturally found in citrus oils and is widely used in the fragrance and flavor industries due to its strong fruity and citrus-like aroma. As a versatile chemical intermediate, it is also utilized in the synthesis of other organic compounds. Industrial production of 1-octanal typically involves the oxidation of 1-octanol or through hydroformylation of 1-heptene. Its applications span across various sectors, including cosmetics, food additives, and pharmaceuticals.
Physical and Chemical Properties
1-Octanal is a colorless to pale yellow liquid with a characteristic fruity odor. It has a density of 0.821 g/cm³ at 20°C and a boiling point between 171-173°C. The compound is soluble in common organic solvents like alcohol and ether but has limited solubility in water. Chemically, 1-octanal is reactive due to its aldehyde functional group, making it susceptible to oxidation and polymerization under certain conditions. It is flammable and should be handled with care to avoid exposure to open flames or high temperatures.
Main Applications
The primary use of 1-octanal is in the fragrance industry, where it imparts citrus and floral notes to perfumes and personal care products. It is also employed as a flavoring agent in food products, contributing to orange and other fruit flavors. In chemical synthesis, 1-octanal serves as a precursor for producing alcohols, acids, and other derivatives. Its applications extend to the manufacturing of plasticizers, lubricants, and surfactants.
Safety and Storage
1-Octanal is classified as an irritant and can cause skin and eye irritation upon contact. Proper personal protective equipment, including gloves and goggles, should be worn when handling this chemical. Inhalation of vapors should be avoided, and adequate ventilation is necessary in work areas. Storage conditions for 1-octanal include keeping it in tightly sealed containers in a cool, dry, and well-ventilated place, away from oxidizing agents and sources of ignition. Shelf life is typically several years when stored under recommended conditions.
B2B Procurement Guide
When procuring 1-octanal, buyers should prioritize suppliers who provide detailed product specifications, including purity levels (commonly 95-99%). Packaging options range from small bottles to bulk drums, depending on the required quantity. Certifications such as ISO, GMP, or REACH compliance are indicators of a reliable supplier. Price negotiations should consider factors like order volume, delivery terms, and payment conditions. Sample testing is recommended to ensure product quality before large-scale purchases.
