3-Hydroxybenzoic acid is a component of castoreum, the exudate from the castor sacs of the mature North American beaver (Castor canadensis) and the European beaver (Castor fiber), used in perfumery. It can also be formed by a Pseudomonas species from 3-Chlorobenzoic acid. [2] 3-Hydroxybenzoic Acid can be found in the pineapple fruit as well.
4-Hydroxybenzoic acid, also known as p-hydroxybenzoic acid (PHBA), is a monohydroxybenzoic acid, a phenolic derivative of benzoic acid.It is a white crystalline solid that is slightly soluble in water and chloroform but more soluble in polar organic solvents such as alcohols and acetone. 4-Hydroxybenzoic acid is primarily known as the basis for the preparation of its esters, known as parabens ...
It is prepared by disulfonation of benzoic acid followed by hydrolysis of the disulfonate. [ 3 ] It is a metabolite of alkylresorcinols , first identified in human urine [ 4 ] and can be quantified in urine [ 5 ] and plasma, [ 6 ] and may be an alternative, equivalent biomarker of whole grain wheat intake.
Included in that class are substances containing a phenolic ring and an organic carboxylic acid function (C6-C1 skeleton). Two important naturally occurring types of phenolic acids are hydroxybenzoic acids and hydroxycinnamic acids, which are derived from non-phenolic molecules of benzoic and cinnamic acid, respectively.

Hydroxybenzoic acid may refer to several related chemical compounds: 2-Hydroxybenzoic acid (salicylic acid, o-hydroxybenzoic acid) 3-Hydroxybenzoic acid (m ...
Benzoic acid is cheap and readily available, so the laboratory synthesis of benzoic acid is mainly practiced for its pedagogical value. It is a common undergraduate preparation. Benzoic acid can be purified by recrystallization from water because of its high solubility in hot water and poor solubility in cold water. The avoidance of organic ...
Dihydroxybenzoic acids (DHBA) are a type of phenolic acids. There are six main compounds, having all the same molecular formula C 7 H 6 O 4. Those are: 2,3-Dihydroxybenzoic acid (2-Pyrocatechuic acid or hypogallic acid) 2,4-Dihydroxybenzoic acid (β-Resorcylic acid) 2,5-Dihydroxybenzoic acid (Gentisic acid) 2,6-Dihydroxybenzoic acid (γ ...
