Citrinin
Citrinin (CAS 518-75-2, C13H14O5, MW 250.25) is a mycotoxin produced by certain fungi, notably Penicillium citrinum. It exhibits a characteristic yellow crystalline appearance and has been a subject of interest in biochemical research. Citrinin is primarily utilised in scientific studies related to cell biology, cell signaling, and lipid metabolism, owing to its known biological activities. It is supplied by Tech Serve Solutions for research and development purposes.
