[Chemical Properties]

Colorless liquid; oily aroma.
[Uses]

Methyl 10-undecenoate is an unsaturated fatty acid ester that can be used as a substrate:
  • To prepare bifunctional polymer precursors via hydroformylation reaction.
  • To synthesize α,ω-ester amides via aminocarbonylation in the presence of palladium catalyst.
  • To modify commercial silicone monomer, 1,3,5,7-tetramethylcyclotetrasiloxane, for the preparation of silicone hollow nano/microstructures in water by hydrosilylation reaction.

[Uses]

Methyl 10-undecenoate, unsaturated fatty acid ester, is used to modify commercial silicone monomer, 1,3,5,7-tetramethylcyclotetrasiloxane for the preparation of silicone hollow nano/microstructures in water.
[Definition]

ChEBI: A fatty acid methyl ester of 10-undecenoic acid.

[General Description]

Methyl 10-undecenoate is the chain stopper in the polymerization of long-chain aliphatic α,ω-diene through acyclic diene metathesis (ADMET). This helps in tuning the molecular weight of the resulting polyester in a range varying from 10 to 45 kDa.
