What is Isobutyl benzene?

Isobutyl Benzene is an organic, aromatic, neutral and colourless liquid that has a specific gravity of around 0.852. It is also known as 2-methyl-1-phenylpropene. Isobutyl benzene or IBB is a colourless chemical compound with a molecular formula C10H14. It is manufactured out of toluene, propylene, methanol, potassium carbonate, sodium among other chemicals. It is a basic organic raw material used widely in the pharmaceutical and perfume industry.

Uses and Applications:

Isobutylbenzene 538-93-2 is widely used in the industrial manufacture of ibuprofen, an analgesic, anti-inflammatory, over the counter painkiller. The acylation of isobutyl benzene and hydrogen fluoride is used in the synthesis of ibuprofen. 4-isobutylacetophenone, an intermediate for the production of ibuprofen is prepared by the acylation of isobutyl benzene 538-93-2. Commercially sold isobutyl benzene has a very wide range of impurities depending on the purity level of the propylene used in the reaction with toluene.

It is a colourless, flammable liquid that is a respiratory irritant. It is used as an international standard in the study of increased pigmentation and floral scents levels in Pap1-transgenic petunia. It is used as a speciality solvent. It can also be used as a solid acid catalyst for the acylation of aromatic substances. Isobutylbenzene is widely used in the synthesis of intermediates like Ortho-Butyl Aniline and Para-Butyl Aniline.

The major commercial use of Isobutylbenzene 538-93-2 after the manufacturing of ibuprofen is in the perfume industry. It has a sweet odour that is fruity, cherry sweet with a balsamic nuance which makes it a basic raw material used in the perfumery industry.
