Overview
Undecanoic Acid, also known as n-Undecanoic Acid, is a saturated fatty acid with a straight-chain structure. It is derived from natural sources such as coconut oil or produced synthetically. The compound is widely used in industrial applications due to its mild odor and chemical stability. As a medium-chain fatty acid, Undecanoic Acid serves as a precursor in the synthesis of esters and other derivatives. Its versatility makes it valuable in industries ranging from food flavoring to pharmaceutical manufacturing.
Physical and Chemical Properties
Undecanoic Acid is a colorless to pale yellow liquid or solid, depending on temperature. It has a density of 0.89 g/cm³ and a melting point between 28-31 °C. The boiling point ranges from 284-286 °C, making it relatively stable under normal conditions. The acid is soluble in organic solvents like alcohol and ether but only slightly soluble in water. Its chemical stability and low reactivity with common reagents make it suitable for various industrial processes. However, it should be handled with care to avoid decomposition at high temperatures.
Main Applications
Undecanoic Acid is primarily used in the production of flavors and fragrances, where it imparts a mild, fatty odor. It is also a key intermediate in the synthesis of plasticizers and lubricants, enhancing the flexibility and durability of materials. In the pharmaceutical industry, Undecanoic Acid is utilized to produce antifungal and antibacterial agents. Its derivatives are often found in topical medications and personal care products. Additionally, it serves as a building block for specialty chemicals in agrochemicals and coatings.
Safety and Storage
Undecanoic Acid should be stored in a cool, dry place, away from direct sunlight and oxidizing agents. Proper ventilation is essential to prevent the accumulation of vapors, which can be irritating to the respiratory system. Personal protective equipment, including gloves and goggles, is recommended when handling the acid. In case of skin contact, wash immediately with soap and water. Dispose of the compound in accordance with local environmental regulations to minimize ecological impact.
B2B Procurement Guide
When procuring Undecanoic Acid, buyers should verify the CAS number (112-37-8) and request certificates of analysis to confirm purity levels. Bulk purchases often qualify for discounts, so it is advisable to negotiate pricing based on volume. Reliable suppliers should provide detailed safety data sheets (SDS) and storage recommendations. Buyers may also inquire about custom packaging options to meet specific logistical requirements. Always source from reputable manufacturers to ensure consistent quality and compliance with industry standards.
