  • n-Heptanoic acid is used primarily:
  • In the form of esters: industrial lubricants (aviation, refrigeration, etc.),
  • Plasticizers for laminated glass, tracer for butter etc.
  • In the form of salts: for aqueous anticorrosion.
  • As raw material for perfume, medicine and lubricating grease.
  • As chemical intermediate in the synthesis of emollient agents:
  • In personal care: propylene glycol diheptanoate & stearyl heptanoate
  • In pharmaceutical gel: neopentylglycol diheptanoate.
  • Thanks to its good anti-corrosion properties and its unique performance level at high and low temperatures, the  n-heptanoic acid and its ester is mainly used in refrigeration lubricants, aviation, automobile…
  • Its ester derivatives are used in the fragrance and flavor industries as well as cosmetics
  • It is used to prepare sodium heptanoate, which is used as a corrosion inhibitor.
