2,3-Dihydroxybenzoic acid Chemical Properties,Usage,Production

Chemical Properties

Pale Brownish to Red Brownish Crystalline Powder. 2,3-Dihydroxybenzoic Acid [303-38-8], C7H6O4, Mr 154.1, mp 206℃, undergoes decomposition to catechol and carbon dioxide. The acid crystallizes from water as a dihydrate. Among other uses, it serves as an iron-complexing agent in drugs.

Uses

2,3-Dihydroxybenzoic Acid is a selected phenol as MMP (Matrix Metalloproteinase) inhibitor.

Uses

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.

Definition

ChEBI: A dihydroxybenzoic acid that is benzoic acid substituted by hydroxy groups at positions 2 and 3. It occurs naturally in Phyllanthus acidus and in the aquatic fern Salvinia molesta.

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.
