Detailed Product Description:

Isobutyric acid, also known as 2-methylpropanoic acid, is a carboxylic

acid.  It is a clear liquid with a somewhat unpleasant smell, boiling at

155 °C and with a specific gravity of 0.9697.  Soluble in water,

alcohol, and ether.

Grade & Purity:

This is FCC/Kosher certified material with purity greater than 99%.

Background:

Isobutyric acid is an isomer of n-butyric acid which has the same

chemical formula but with a different structure.  It is found in the

free state in carobs (Ceratonia siliqua), in the root of Arnica dulcis,

and as an ethyl ester in croton oil.

Application Notes:

Typically used in the manufacture of esters for solvents, flavors,

and perfume bases.  Also found in disinfecting agents, varnishes,

tanning agents, and for de-liming hides.

Heated with chromic acid solution to 140 °C, it dissociates into carbon

dioxide and acetone.  Alkaline potassium permanganate oxidizes it to

á-hydroxyisobutyric acid. 

Precautions:

Combustible.  Toxic by ingestion.  Strong irritant to eyes and tissue.
