CAS: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.Formula:C7H6O3Molecular weight:138.124-Hydroxybenzoic acid
