Barbituric acid, 99%, Thermo Scientific Chemicals

Description

Barbituric acid is widely used in the manufacturing of plastics, textiles, polymers and pharmaceuticals. It is an active ingredient in the production of Vitamin B₂. It is a strong acid in an aqueous medium with an active methylene group involved Knoevenegal condensation. It is used as precursor for the preparation of 5-arylidene barbituric acid by reacting with aromatic aldehyde. It is also used in electrochemical oxidation of iodine using cyclic voltammetry and controlled potential coulometry.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
