For professionals in chemical procurement and research, a thorough understanding of a compound's properties and handling procedures is fundamental. Ethyl Acetoacetate (CAS 141-97-9), a widely used beta-keto ester, possesses characteristics that make it both valuable and requiring careful management. This guide provides insights into its physical and chemical properties, safety considerations, and the best practices for sourcing this important industrial chemical.

Ethyl Acetoacetate is typically a colorless liquid with a characteristic fruity or rum-like odor. Its chemical formula is C6H10O3, and it has a molecular weight of 130.14 g/mol. Key properties include a boiling point of approximately 181°C and a density of around 1.03 g/mL at 20°C. It exhibits keto-enol tautomerism, a critical aspect for its reactivity in various organic synthesis pathways, such as the acetoacetic ester synthesis. This versatility makes it a sought-after intermediate for pharmaceutical, dye, and fragrance applications.

From a safety perspective, Ethyl Acetoacetate is classified as an irritant, particularly to the eyes and respiratory system, and is flammable. Proper handling necessitates good ventilation, avoiding ignition sources, and wearing appropriate personal protective equipment (PPE) such as gloves and safety glasses. When looking to buy Ethyl Acetoacetate, ensuring your supplier provides a comprehensive Material Safety Data Sheet (MSDS) is crucial for safe storage and handling protocols.

When sourcing this chemical, it is advisable to partner with a reputable manufacturer or supplier who can guarantee product quality and provide necessary safety information. Companies often seek competitive price points from bulk purchasers. Inquiring about grades and purity levels directly from a manufacturer in China can offer significant advantages. For consistent and safe use, always refer to the supplier's technical data and safety guidelines before commencing any work with Ethyl Acetoacetate.
