BENZIL FOR SYNTHESIS
- Part number
- RXSOL-60-6604-041
- Category
- Lab Chemical
- Brand
- RXSOL
Overview
Benzil is a standard building block in organic synthesis. It condenses with amines to give diketimine ligands. A classic organic reaction of benzil is the benzilic acid rearrangement, in which base catalyses the conversion of benzil to benzilic acid.

Applications
Benzil is used in the free-radical curing of polymer networks. Ultraviolet radiation decomposes benzil, generating free-radical species within the material, promoting the formation of cross-links. Benzil is a potent inhibitor of human carboxylesterases, enzymes involved in the hydrolysis of carboxylesters and many clinically used drugs.
Dosage and directions
Benzil is a standard building block in organic synthesis. It condenses with amines to give diketimine ligands. A classic organic reaction of benzil is the benzilic acid rearrangement, in which base catalyses the conversion of benzil to benzilic acid. This reactivity is exploited in the preparation of the drug phenytoin. Benzil also reacts with 1,3-diphenylacetone in an aldol condensation to give tetraphenylcyclopentadienone.
Characteristics and notes
BENZIL FOR SYNTHESIS provides benefits i.e. greater solubility in water, less cost. Thiamine hydrochloride catalyzed synthesis of benzoin from benzaldehyde.
