| | 2-Benzoylbenzoic acid Usage And Synthesis |
| 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. | | Synthesis Reference(s) | Journal of the American Chemical Society, 70, p. 2758, 1948 DOI: 10.1021/ja01188a035

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).
