Colistin sulfate is a polymyxin antibiotic derived from *Bacillus polymyxa*, primarily used in veterinary medicine to treat gram-negative bacterial infections, including those resistant to other antibiotics. It is also applied in aquaculture and occasionally in human medicine under strict supervision due to its nephrotoxicity and neurotoxicity risks. This chemical has a CAS number of 1264-72-8, with the molecular formula C52H98N16O13·H2SO4 and a molecular weight of 1253.51 g/mol. It must be stored between 2 to 8°C and carries a **Danger** signal word due to its hazardous properties. Molekula supplies Colistin Sulfate from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
