Rapamycin, universally recognized as Sirolimus and bearing the CAS number 53123-88-9, is a compound of considerable interest within the pharmaceutical and chemical industries. Its intricate structure as a macrolide antibiotic, coupled with its powerful immunosuppressive and antifungal attributes, positions it as a critical pharmaceutical intermediate. As a manufacturer deeply involved in its production and supply, we provide an overview of its key properties and applications.

The molecular identity of Rapamycin is defined by its formula C51H79NO13 and a molecular weight of 914.17200. Typically appearing as a yellow to off-white solid, it possesses a melting point between 183-185°C. Importantly, Rapamycin is noted for its stability when stored appropriately, a crucial factor for its use in pharmaceutical manufacturing. Its solubility in organic solvents such as DMSO and methanol, contrasted with its insolubility in water, guides its application in various chemical synthesis processes.

The therapeutic significance of Rapamycin is profound, primarily for its role in preventing organ transplant rejection, a cornerstone of modern transplant medicine. Its mechanism of action, which involves modulating immune responses, also makes it valuable in treating autoimmune conditions. Furthermore, its antifungal and antineoplastic properties are continually being explored in research aimed at developing new treatments for infections and cancers.

The potential applications of Rapamycin extend beyond these established uses, with ongoing studies investigating its impact on cellular aging and its role in neurological disorders. This broad spectrum of research underscores the compound's versatility and its potential to drive future medical breakthroughs.
