For chemists and researchers engaged in complex molecular synthesis, a thorough understanding of a compound's reactivity is fundamental to successful outcomes. 1-(2-Hydroxyethyl)-1H-pyrrole-2,5-dione, identified by its CAS number 1585-90-6, is a molecule whose dual functionality offers a rich landscape for chemical transformations. This compound is widely utilized across various sectors, from pharmaceuticals to advanced materials, due to the predictable and versatile reactivity of its maleimide and hydroxyethyl groups. As a leading manufacturer and supplier, we provide this essential reagent with the quality and purity necessary for precise chemical reactions.

The core of 1-(2-Hydroxyethyl)-1H-pyrrole-2,5-dione's reactivity lies in its maleimide functionality. The electron-deficient double bond within the maleimide ring is a potent Michael acceptor, exhibiting strong affinity and rapid reaction kinetics with thiols. This thiol-maleimide conjugation is a cornerstone of bioconjugation, forming stable thioether linkages. The reaction proceeds efficiently under mild physiological conditions (pH 6.5-7.5), making it ideal for modifying sensitive biomolecules like proteins and peptides. Beyond thiols, the maleimide group can also react with other nucleophiles, albeit typically with slower rates or requiring specific conditions. For professionals looking to buy this compound for demanding applications, understanding these reactivity profiles is crucial for selecting optimal reaction conditions and partners.

Complementing the maleimide group is the hydroxyethyl substituent. The terminal hydroxyl group offers a site for various chemical modifications. It can undergo typical alcohol reactions, such as esterification, etherification, and acylation. This allows for the attachment of diverse functional groups, polymers, or labels to the molecule, or the extension of linker chains. For instance, the hydroxyl group can be converted into an activated ester for subsequent amine coupling, or it can be used as an initiator for polymerization. This versatility allows chemists to tailor conjugates or materials to specific requirements, enhancing their utility in areas like drug delivery or sensor development. Our commitment as a supplier is to provide 1-(2-Hydroxyethyl)-1H-pyrrole-2,5-dione at 98% purity, ensuring consistent and predictable reactivity in all these transformations.

The synthesis of complex molecules often requires careful sequential reactions, leveraging the orthogonal reactivity of different functional groups. 1-(2-Hydroxyethyl)-1H-pyrrole-2,5-dione excels in such strategies, where the maleimide can react selectively with thiols, while the hydroxyl group can be protected or derivatized independently.
