For procurement managers and R&D scientists in the chemical industry, a thorough understanding of a compound's properties is fundamental before making a purchase decision. Ethyl 3-aminocrotonate (CAS 626-34-6) is a chemical that demands attention due to its versatile applications, but its handling and optimal use depend on its specific characteristics.

Ethyl 3-aminocrotonate is typically described as an off-white to light yellow solid. Its melting point ranges from 29°C to 35°C, indicating it can exist as a low-melting solid or even a viscous liquid under warmer ambient conditions. The boiling point is around 210-215°C, and it has a flash point of approximately 97°C (closed cup), classifying it as a combustible liquid. Its density is about 1.022 g/mL at 25°C, and its refractive index is 1.499.

Crucially, Ethyl 3-aminocrotonate is noted to be air and moisture sensitive, and hygroscopic. This means it should be stored in tightly closed containers in a dry, well-ventilated area, potentially under an inert atmosphere, and protected from light. Its sensitivity dictates careful handling and storage protocols to maintain its integrity and efficacy. Incompatible substances include strong acids, bases, oxidizing agents, and reducing agents.

From a solubility perspective, it is soluble in water (approximately 26 g/L at 25°C), which can be advantageous for certain aqueous-based reactions or formulations. Its molecular formula is C6H11NO2, with a molecular weight of 129.16 g/mol. These technical details are vital for chemists and formulators when planning synthesis routes or developing new products.

When sourcing Ethyl 3-aminocrotonate, buyers should look for suppliers that clearly state these properties and provide a detailed Safety Data Sheet (SDS). Understanding the price, availability, and manufacturer's reputation are also key aspects of a successful procurement strategy for this essential chemical intermediate. Partnering with a reliable manufacturer ensures you buy a product that meets your specifications.
