For procurement specialists and R&D professionals in the chemical and pharmaceutical sectors, a thorough understanding of chemical properties and reliable sourcing is key. This guide delves into the specifics of Diethyl Maleate (CAS 141-05-9), providing essential information on its characteristics and how to effectively purchase it from reputable suppliers. As a trusted manufacturer, we aim to provide the clarity you need to make informed decisions.

Diethyl Maleate, identified by CAS number 141-05-9, is a colorless, clear liquid at room temperature. Its physical properties include a melting point around -10°C and a boiling point of approximately 225°C. It is characterized by a distinct fruity odor, often described as banana or citrus-like, though its use in fragrance applications is now restricted due to sensitization concerns. Importantly for many industrial applications, Diethyl Maleate is insoluble in water but readily soluble in common organic solvents like ethanol and ether. This solubility profile is a critical factor for its use in various reaction media and formulations.

Chemically, Diethyl Maleate is an ester of maleic acid. Its structure features an alpha, beta-unsaturated carbonyl system, making it reactive and valuable in a range of chemical processes. It is widely employed as a dienophile in Diels-Alder cycloaddition reactions, a fundamental pathway in organic synthesis for building complex molecular architectures. This reactivity also makes it a useful intermediate for creating polymers, resins, and other specialty chemicals.
