General description

Hexanoic acid is a resistance priming inducer that protects tomato plants from Botrytis cinerea.

Application

Hexanoic acid can be used:
  • To prepare polyethylene glycol derived nanomicelles as a non-viral gene carrier.
  • As a starting material to synthesize an amino acid L-norleucine.
  • As a reactant to prepare 4-methoxy phenyl hexyl ketone through Friedel−Crafts acylation of anisole using Hβ zeolite-based catalyst.
  • As a template in the preparation of highly conducting thin polypyrrole coated alumina composite particles.
