(1S,3R,5E,7E,22E)-1,3-Bis{[dimethyl(2-methyl-2-propanyl)silyl]oxy}-9,10-secoergosta-5,7,10,22-tetraene(CAS: 111594-58-2)

The compound exhibits a crystalline form with a molecular weight of approximately 722.4 g/mol. Its solubility in common organic solvents is moderate. Chemically, it shows moderate reactivity towards hydrogenation and can undergo typical silylation reactions. It is not highly reactive but requires careful handling due to its silyl functional groups.

This compound is usually synthesized via a silylation reaction of ergosta-5,7,10,22-tetraen-9-one with dimethyl(2-methyl-2-propanyl)silane under basic conditions. Common catalysts include sodium hydride, and the reaction typically yields a 90% isolated yield. The product is purified by column chromatography.

This compound is primarily used in pharmaceuticals for its potential as a precursor in the synthesis of biologically active molecules. It may also find applications in the production of speciality chemicals and as a research reagent in organic chemistry labs.

Handling this compound requires the use of personal protective equipment (PPE) including gloves, safety goggles, and a lab coat. It should be stored in a cool, dry place away from direct sunlight. Spills should be cleaned up with caution, using appropriate spill kits, and the area should be ventilated. Always refer to the Safety Data Sheet (SDS) for detailed guidelines on handling and disposal.
