Overview
Undecanol, also known as 1-undecanol or n-undecanol, is a fatty alcohol with the molecular formula C11H24O. It is a colorless liquid with a mild odor and is commonly used in industrial applications. Undecanol is part of a larger family of fatty alcohols, which are widely utilized in the production of fragrances, flavors, and surfactants. Fatty alcohols like undecanol are derived from natural fats and oils or through synthetic processes. They serve as important intermediates in the chemical industry, contributing to the production of various consumer and industrial products. Undecanol, in particular, is valued for its stability and low volatility.
Physical and Chemical Properties
Undecanol is a colorless liquid with a density of approximately 0.83 g/cm³. It has a melting point of 16-18°C and a boiling point of 243°C. The compound is insoluble in water but dissolves readily in organic solvents such as ethanol and ether. Key chemical properties of undecanol include its mild odor and low volatility, making it suitable for use in fragrances and flavors. Its stability under normal conditions ensures it can be stored and handled with relative ease, though proper precautions should still be observed.
Main Applications
Undecanol is primarily used in the fragrance and flavor industry, where it serves as a key ingredient in the formulation of perfumes and food additives. Its mild odor and stability make it an ideal choice for these applications. In addition to fragrances and flavors, undecanol is used in the production of plasticizers and surfactants. These compounds are essential in manufacturing processes for plastics, detergents, and other industrial products. The versatility of undecanol underscores its importance in various chemical applications.
Safety and Storage
Undecanol should be stored in a cool, dry, well-ventilated area away from heat sources and open flames. Proper handling includes the use of personal protective equipment (PPE) such as gloves and safety goggles to avoid skin and eye contact. While undecanol is not highly toxic, prolonged exposure or ingestion can cause irritation. In case of contact, rinse thoroughly with water and seek medical attention if necessary. Always follow safety data sheets (SDS) and regulatory guidelines when handling this chemical.
B2B Procurement Guide
When procuring undecanol, it is essential to verify the CAS number (112-42-5) and purity requirements to ensure the product meets your specifications. Suppliers should provide certificates of analysis (CoA) and compliance with relevant regulations. Prices for undecanol typically range from $20 to $50 per kg, depending on purity and supplier. Bulk purchases may offer cost savings, but always assess the supplier's reliability and quality control measures. Consider logistical factors such as shipping and storage conditions to maintain product integrity.
