Hydrocortisone 21-aldehyde hydrate (Cat No.:C000791) is a chemical mixture containing both the aldehyde and hydrated forms of hydrocortisone, a glucocorticoid steroid with anti-inflammatory and immunosuppressive properties. This complex compound likely holds significance in pharmaceutical research and synthesis. The presence of the aldehyde and hydrated forms suggests a dynamic equilibrium between the two states. Researchers may investigate its stability, reactivity, and potential interactions with biological systems.
