The compound (2R,3R)-2,3-dihydroxybutanedioic acid, methyl (1S,4R)-4-aminocyclopent-2-ene-1-carboxylate, identified by CAS number 419563-22-7, stands as a pivotal pharmaceutical intermediate. Also known by synonyms such as (1S,4R)-Methyl 4-aminocyclopent-2-enecarboxylate L-tartrate salt and (1S,4R)-Methyl 4-aminocyclopent-2-enecarboxylate (2R,3R)-2,3-dihydroxysuccinate, this high-purity compound is typically found as an off-white to light beige solid. Its critical role lies in the synthesis of Peramivir, a powerful antiviral agent against influenza.

With a molecular formula of C11H17NO8 and a molecular weight of 291.26, this compound exhibits a precise chemical architecture. It possesses a high boiling point of 499.3 degrees Celsius at 760 mmHg and a flash point of 255.8 degrees Celsius, indicating its thermal stability. Quality assurance is paramount, with typical specifications showing a purity of greater than or equal to 98% and a maximum moisture content of 0.5%. These robust physical and chemical properties ensure its reliability in demanding pharmaceutical processes, underscoring its value in complex synthetic pathways.

The primary application of this compound is its indispensable function as an intermediate for Peramivir (CAS: 229614-55-5). Peramivir is a critical neuraminidase inhibitor, playing a vital role in curbing the spread of influenza viruses within the human body. The precise stereochemistry of the intermediate, particularly its (1S,4R) and (2R,3R) configurations, is absolutely essential for the chiral synthesis of Peramivir. This specificity ensures that the final drug product possesses the required biological activity and efficacy, making the intermediate a cornerstone in antiviral drug development and production.

Maintaining the integrity of this specialized chemical requires meticulous storage and handling protocols. It is strongly recommended to store the compound in a -20 degrees Celsius freezer within a cool, dry, and well-closed container. Protection from moisture, strong light, and excessive heat is crucial to prevent degradation and maintain its specified purity and efficacy. The product is commonly packaged in 25kg cardboard drums, though packaging can be tailored to meet specific customer requirements. Adherence to these guidelines is vital for preserving the compound's quality throughout its shelf life, whether for research or industrial scale operations.
