“…Literature values for the melting point of synthetic pyridine-2,6-dicarboxylic acid range from 226 C (Hess and Wissing, 1915) to 235-237 C (Soine and Buchdahl, 1950). Powell (1953) reported 229 C for the bacterial pyridine-2,6-dicarboxylic acid.…”

“…Dipicolinic acid is easily prepared by the pernianganate oxidation of commercially obtainable 2,6-lutidine (6). This oxidation is as easy to perform as the oxidation of a-picoline to a-picolinic acid by permanganate and permits the isolation of the free acid in contrast to a-picolinic acid which is isolated as the hydrochloride.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
