Isopropyl (2E,4E,7S)-11-methoxy-3,7,11-trimethyl-2,4-dodecadienoate(CAS: 65733-16-6)

Isopropyl (2E,4E,7S)-11-methoxy-3,7,11-trimethyl-2,4-dodecadienoate has a crystalline form, with a molecular weight of approximately 344.5 g/mol. It is poorly soluble in water but soluble in organic solvents like ethanol and acetone. Chemically, it is reactive, particularly towards nucleophilic substitution and addition reactions. Its reactivity can be influenced by its methoxy group, trimethyl groups, and double bonds.

This compound can be synthesized via a Wittig reaction, where a phosphonium salt reacts with an aldehyde and methoxy group-containing compound. The reaction typically requires a Lewis acid catalyst like aluminium trichloride. The method yields a predominantly cis-isomer due to the steric hindrance provided by the methyl groups.

This compound is used in the pharmaceutical industry for developing certain drug formulations, and in the polymer industry for modifying the properties of polymers. It is also employed in the sensor technology sector for its reactivity and selectivity towards specific chemical species, and in the semiconductor industry for its potential use as a precursor in organic synthesis.

When handling this compound, use proper personal protective equipment (PPE) including gloves, goggles, and a lab coat. Work in a well-ventilated area or fume hood due to its potential for inhalation hazards. Spills should be contained and cleaned up with appropriate absorbent materials, and contact with skin or eyes should be avoided. Refer to the Material Safety Data Sheet (MSDS/SDS) for detailed safety information.
