[2-Hydroxy-3-[2-hydroxy-3-[2-hydroxy-3-[2-hydroxy-3-[2-hydroxy-3-[2-hydroxy-3-[(Z)-octadec-9-enoyl]oxypropoxy]propoxy]propoxy]propoxy]propoxy]propyl] (Z)-octadec-9-enoate(CAS: 76009-37-5)

The compound is a highly branched, cyclic ester. It has a molecular weight of approximately 924.15 g/mol. It is sparingly soluble in water and ethanol but more soluble in organic solvents like dichloromethane. It is hydrolytically stable under neutral and acidic conditions but can undergo transesterification in basic conditions. It is a non-toxic compound with a pKa around 10.5.

This compound is synthesized through a series of Michael addition reactions involving a cyclic enone and a reducing agent followed by esterification. The key steps involve the use of a zinc amalgam reduction to form the corresponding alcohol, and then subsequent Michael addition reactions with cyclic enone derivatives, followed by esterification with octadec-9-enoic acid. The overall yield is moderate, around 50-60%, and the selectivity is high.

This compound finds applications in the pharmaceutical industry, where it can serve as a building block for drug synthesis. It is also used in polymer chemistry for the modification of polymers to improve their biocompatibility and functional properties. Additionally, it is explored in the development of sensors and semiconductors due to its unique chemical structure.

When handling this compound, it is important to use appropriate personal protective equipment (PPE) including gloves, goggles, and laboratory coats to protect against skin and eye contact. Ensure adequate ventilation and use a fume hood during operations. In case of a spill, immediately clean up with appropriate absorbent materials and dispose of according to local regulations. Always refer to the Safety Data Sheet (SDS) for detailed handling and disposal guidelines.
