Isobutyraldehyde CAS#78-84-2
Isobutyraldehyde, also known as 2-Methylpropanal, is an organic compound belonging to the family of aldehydes, which can be found in alcoholic beverages, tea, breads, cooked pork, spearmint oil as well as fresh fruits, such as apple, banana, cherry, etc. It is manufactured by the hydroformylation of propene, usually obtained as a side-product. It can be applied as a source for producing other chemicals, including isobutyl alcohol, neopentyl glycol as well as isobutanoic acid production and used to produce amino acids such as valine and leucine. Besides, isobutyraldehyde commonly serves as an intermediate in the field of chemical industry for manufacture of pharmaceuticals (such as Vitamin B5), crop protection products, pesticides, synthetic resins, antioxidants, vulcanisation accelerators, textile auxiliaries, perfumery and flavors.
