Molekuchine, also known as colchicine, is a tropolone alkaloid with anti-inflammatory properties, used as a gout suppressant and in the treatment of crystal-induced joint inflammation and familial Mediterranean fever, and in research as a tubulin-binding, microtubule-depolymerizing agent. This chemical is a natural alkaloid obtained from Colchicum autumnale (autumn crocus). It has a CAS number of 64-86-8, with a molecular formula of C22H25NO6 and a molecular weight of 399.44. It is typically stored at ambient conditions, though it requires careful handling due to its hazardous nature, as indicated by its "Danger" signal word. Molekula supplies Molekuchine from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
