Benzoic acid and its salts are used as food preservatives, represented by the E numbers E210, E211, E212, and E213. Benzoic acid inhibits the growth of mold, yeast [23] and some bacteria. It is either added directly or created from reactions with its sodium, potassium, or calcium salt. The mechanism starts with the absorption of benzoic acid ...
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 ...
p-Anisic acid, also known as 4-methoxybenzoic acid or draconic acid, is one of the isomers of anisic acid. The term "anisic acid" often refers to this form specifically. [ 1 ] It is a white crystalline solid which is insoluble in water, highly soluble in alcohols, and soluble in ether and ethyl acetate .
4-Chlorobenzoic acid is an organic compound with the molecular formula ClC 6 H 4 CO 2 H. It is a white solid that is soluble in some organic solvents and in aqueous base. 4-Chlorobenzoic acid is prepared by oxidation of 4-chlorotoluene .
Pentafluorobenzoic acid (PFBA) is an organofluorine compound with the formula C 6 F 5 CO 2 H. It is a white crystalline powder that has a high solubility in water. Its pK a of 1.48 indicates that it is a strong acid. [1]
4-Fluorobenzoic acid (p-fluorobenzoic acid) is an organic compound with the formula C 7 H 5 FO 2. This colourless solid is a derivative of benzoic acid carboxylic acid. It is a synthetic intermediate.
