Overview
n-Hexyl Acetoacetate is an organic ester derived from acetoacetic acid and n-hexanol. It is widely recognized for its fruity aroma, making it a popular choice in the flavor and fragrance industry. This compound also serves as a versatile intermediate in organic synthesis, particularly in the production of pharmaceuticals and specialty chemicals. Its chemical stability and solubility in common organic solvents enhance its utility in various industrial applications. The compound is typically synthesized through esterification reactions, ensuring high purity for commercial use.
Physical and Chemical Properties
n-Hexyl Acetoacetate is a colorless to pale yellow liquid with a characteristic fruity odor. It has a molecular weight of 186.25 g/mol and a density ranging between 0.96 and 0.98 g/cm³. The compound boils at approximately 220-225°C, though its melting point is not well-documented. It is soluble in most organic solvents, including ethanol and ether, but exhibits limited solubility in water. These properties make it suitable for formulations requiring hydrophobic or solvent-based systems. Its stability under normal conditions ensures long shelf life when stored properly.
Main Applications
The primary use of n-Hexyl Acetoacetate is in the flavor and fragrance industry, where it imparts fruity notes to perfumes, cosmetics, and food products. Its pleasant aroma makes it a preferred ingredient in synthetic flavorings. In organic synthesis, it acts as a key intermediate for producing pharmaceuticals, agrochemicals, and other specialty chemicals. Its reactivity allows for the formation of complex molecules, contributing to advancements in medicinal chemistry and material science.
Safety and Storage
n-Hexyl Acetoacetate should be handled with care to avoid inhalation or skin contact, as it may cause irritation. Proper personal protective equipment (PPE), such as gloves and goggles, is recommended during handling. Storage conditions include keeping the compound in a cool, dry, and well-ventilated area, away from heat sources and open flames. Containers should be tightly sealed to prevent moisture absorption and contamination. In case of spills, absorb with inert material and dispose of according to local regulations.
B2B Procurement Guide
When procuring n-Hexyl Acetoacetate, buyers should prioritize suppliers with verified certifications and a track record of quality. Key factors to consider include purity levels (typically 98% or higher), CAS number verification, and packaging options. Bulk purchases may offer cost advantages, but storage capacity and shelf life should be evaluated. Requesting samples for quality testing before large-scale orders is advisable. Additionally, ensure compliance with regional regulatory requirements for chemical imports and usage.
