Allyl Chlorooxalate CAS 74503-07-4
High-Purity Allyl Chlorooxalate CAS 74503-07-4 from Aure Chemical: Stable Supply & Compliance
Allyl chlorooxalate is a reactive liquid ester-acid chloride that combines allyl and oxalyl functionalities, making it valuable for selective acylation and cross-coupling reactions in complex molecule synthesis. It is particularly important in the construction of beta-lactam frameworks found in modern antibiotics. The compound's dual reactivity demands careful handling under inert or controlled conditions to maintain stability and prevent decomposition.
Its primary role lies in enabling efficient routes to advanced pharmaceutical intermediates where traditional reagents may lack the required selectivity or functional group compatibility. Aure Chemical supplies material meeting the stringent purity requirements of API manufacturing. Storage under cool, dry, and inert conditions helps preserve product quality during global distribution.
