(11beta)-21-Acetoxy-11-hydroxy-3,20-dioxopregn-4-en-17-yl propionate(CAS: 74050-20-7)

This compound is a crystalline solid with a molecular weight of approximately 412.44 g/mol. It has a low solubility in water but is more soluble in organic solvents like ethanol and acetone. It is moderately reactive, particularly in acidic conditions. The compound exhibits a characteristic melting point around 150-155°C and is stable under normal conditions.

This compound is typically synthesized through a series of reactions involving the acetylation of progesterone followed by esterification with propionic acid. The synthesis involves precise control over temperature and pH, with the use of a catalytic amount of a strong acid like sulfuric acid to facilitate the acetylation step. The product is purified using column chromatography and recrystallization techniques.

This compound is primarily used in the pharmaceutical industry, where it serves as an intermediate in the synthesis of progestins and other steroid hormones. It has applications in research and development, particularly in the formulation of contraceptives and hormone replacement therapies.

When handling this compound, it is crucial to wear appropriate personal protective equipment (PPE), including gloves, safety goggles, and lab coats. It should be stored in a well-ventilated area, away from heat and sources of ignition. In case of a spill, use appropriate spill response materials, and consult the Safety Data Sheet (SDS) for detailed instructions.
