4-Hydroxybenzoic acid (Standard)

CAS: 99-96-7

4-Hydroxybenzoic acid (Standard) is a reference standard for research and analysis in studies involving 4-Hydroxybenzoic acid. 4-Hydroxybenzoic acid (4-hydroxybenzoate) 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. It could inhibit most gram-positive and some gram-negative bacteria, with an IC50 of 160 μg/mL.

4-Hydroxybenzoic acid

CAS: 99-96-7

4-Hydroxybenzoic acid is a plant metabolite that is found in many plants and fruits. 4-Hydroxybenzoic acid has been shown to have anti-diabetic effects in vitro. This compound also has anti-inflammatory properties, which may be due to its ability to inhibit the production of effector proteins such as nitric oxide synthase and cyclooxygenase. The biological activity of 4-hydroxybenzoic acid is dependent on the concentration; at low concentrations it inhibits glucose uptake by cells, while at high concentrations it prevents cell growth.
