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.

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.]
