2-Benzoylbenzoic acid Chemical Properties,Usage,Production

Synthesis

In the presence of aluminum trichloride, phthalic anhydride and benzene are condensed and obtained by hydrolysis. The hydrochloric acid gas by-product in the reaction should preferably be absorbed into dilute hydrochloric acid for subsequent use. The industrial benzoylbenzoic acid is white to beige powder, the purity is above 97%, and the initial melting point of the dry product is ≥126.0%.

Chemical Properties

ALMOST WHITE TO SLIGHTLY BEIGE CRYSTALLINE POWDER

Uses

2-Benzoylbenzoic Acid is a reagent that is used in the synthesis of BzATP Triethylammonium Salt, which is a selective P2X purinergic agonist. It is more potent than ATP at homodimeric P2X7 receptors.

The Journal of Organic Chemistry, 39, p. 2051, 1974 DOI: 10.1021/jo00928a016

Flammability and Explosibility

Not classified

Safety Profile

Moderately toxic by ingestion.When heated to decomposition it emits acrid smoke andirritating vapors.

Purification Methods

Recrystallise the acid from *C6H6 or cyclohexane, but it is best recrystallised by dissolving in a small volume of hot toluene and then adding just enough pet ether to cause turbidity, and cool. Dry it in a low vacuum at 80o. It can be sublimed at 230-240o/0.3mm [Bray et al. J Chem Soc 265 1957]. The S-benzylisothiuronium salt has m 177-178o (from EtOH). [Lewenz & Serijan J Am Chem Soc 75 4087 1953, Beilstein 10 H 747, 10 IV 2977.]
