Citric Acid Powder - Anhydrous, Lab Grade, 99+% Purity

Citric acid, anhydrous, is supplied as a lab grade crystalline powder at 99+% purity. The anhydrous form carries no water of crystallization, which keeps assay consistent and makes it straightforward to weigh for solution work and formulation.

It is used as an acidulant and antioxidant in food and beverage work, as a chelating agent for metal ions in cleaning and descaling, as a pH buffer component in cosmetics and plating baths, and in brewing for acid adjustment. It also serves as a mild etchant and as a rust and scale remover on metal surfaces.
