And the article was published in Synthesis in 2019. Safety of 4-Bromobenzoic acid The author mentioned the following in the article:
A facile method for the construction of esters R1C(O)OR2 [R1 = Et, Ph, 2-furyl, etc.; R2 = Et, cyclohexyl, Bn, etc.] through dehydrative coupling of carboxylic acids with alcs. was developed. The reactions were mediated by sulfuryl fluoride (SO2F2) at room temperature and proceeded with high efficiency. The method had several advantages including broad substrate scope, mild conditions, excellent functional group compatibility and afforded high yields, even on gram scale. In the experimental materials used by the author, we found 4-Bromobenzoic acid(cas: 586-76-5Safety of 4-Bromobenzoic acid)
4-Bromobenzoic acid(cas: 586-76-5) has been used to study the metabolic fate of 2-,3-and 4-bromo benzoic acids in rat hepatocytes incubation using high temperature liquid chromatography.Safety of 4-Bromobenzoic acid It was used in bromine-specific detection of the metabolites of 2-,3-and 4-bromobenzoic acid in the urine and bile of rats by inductively coupled plasma mass spectrometry.
