Applications and use

Isobutyl aldehyde is used as a raw material in the production of alcohols, acids, amines and esters. It is used in the production processes of plasticizers, pharmaceuticals, plant protection products, synthetic resins, odorising agents, solvents and various types of additives used in many industries (antioxidants, wetting agents, components of perfumes, improvers).

The substance has been registered as an intermediate product requiring isolated transportation and, according to the REACH ordinance, may be used as a substance which is used up or applied solely for chemical processing in order to be converted into another substance.

Identified uses (REACH): intermediate product.

Packing and transportation

Requirements for storage structures:
  • Meeting the Directive 94/9/EC as regards protection equipment and systems for use in potentially explosive atmosphere.
  • Meeting Directive 1999/92/EC as regards minimum requirements to ensure safety and health of employees in zones with potential explosion hazard.
  • Local exhaust ventilation to extract vapours from the places of their emission, and general room ventilation.
  • Impermeable floor to allow collection of spills and prevent penetration into the sewerage system.


  • Store in leak-tight tanks in neutral atmosphere, e.g. under a nitrogen blanket.
  • Use only tools made to non-sparking standards and equipment made to EX standards.
  • Do not smoke and do not use open fire.
  • Eliminate all sources of ignition.
  • Fire extinguishers should be easily accessible in the storage area.
  • Use only under conditions closely controlled according to the ordinance (EC) No. 1907/2006, Article 18 (4).

Other notes.

Incompatible substances: bases, acids, oxidising agents, some amines and alcohols.
Organic fibrous materials contaminated with isobutyl aldehyde may ignite in contact with air. 

Violent, exoenergic reaction may develop in the presence of bases and many organic substances, such as alcohols, amines, oxidising agents and acids.
Vapours of isobutyl aldehyde are heavier than air and may travel long distances away from the source of ignition.
