Description

Application

2,3-Dihydroxybenzoic acid was used to study the complexes of manganese with aliphatic and aromatic polyhydroxy ligands in basic media by electrochemical, spectrophotometric and magnetic methods. It was used in isolation of new siderophore named vulnibactin from low iron cultures of Vibrio vulnificus, a human pathogen. It was used as cocrystal former to study the influence of position isomerism on the co-crystals formation and physicochemical properties of piracetam.

Biochem/physiol Actions

2,3-Dihydroxybenzoic acid was found to be orally effective iron-chelating drug in hypertransfused rat model. It is monocatechol siderophore produced by Brucella abortus.
