Nystatin dihydrate is a polyene antifungal antibiotic used primarily to treat fungal infections, particularly those caused by *Candida* species, in topical and oral formulations. It binds to ergosterol in fungal cell membranes, disrupting integrity and leading to cell death. This chemical is available as a white to off-white powder with the CAS number 1400-61-9, molecular formula C47H75NO17·2H2O, and a molecular weight of 962.10 g/mol. Store between 2 to 8 °C, with no signal word classification required. Molekula supplies Nystatin dihydrate from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
