4-HYDROXYBENZOIC ACID [RING-14C(U)] - Introduction
The properties of 4-hydroxybenzoic acid [cyclo-14C(U)] are:
chemical formula: C7H6O3
Relative molecular mass: 138.12g/mol
Appearance: White crystalline powder
Melting point: 209-212 ° C
solubility: soluble in alcohol, ether and alkali solution, slightly soluble in water
The main use of 4-hydroxybenzoic acid is as an intermediate in drug synthesis and organic synthesis reagent. It can be used in the preparation of daily chemicals such as sunscreens, moisturizers and foaming agents. In addition, it can also be used in the synthesis of certain organic solvents, coating additives and dyes.
The method for preparing 4-hydroxybenzoic acid is usually oxidation by the reaction of benzoic acid with hydrogen peroxide. Hydrogen peroxide can oxidize benzoic acid to 4-hydroxybenzoic acid under acidic conditions. When the radioactive 14C isotope is added to the reaction, 4-hydroxybenzoic acid [cyclo-14C(U)] is obtained.
Regarding safety information, 4-hydroxybenzoic acid is generally a low-toxic compound, but it is still necessary to pay attention to its safe operation. Contact with skin and eyes may cause irritation and discomfort, so wear protective glasses and gloves when performing operations. At the same time, avoid inhaling its dust or gas. When the compound is used, it should be done in a well-ventilated area with appropriate personal protective measures. Detailed safety information can be obtained from the relevant safety data sheet.
