Oxalic Acid, Dihydrate - Ethanedioic Acid

Product Overview

Oxalic Acid Dihydrate (Ethanedioic Acid) is a high-purity, colorless crystalline solid meeting ACS Reagent Grade specifications. With a formula of C₂H₂O₄·2H₂O, it serves as a potent reducing agent and complexing agent in industrial and laboratory environments. This product maintains a typical assay of 99.0% to 100.5%, ensuring consistent performance for analytical titrations and sensitive manufacturing processes.

Ideally suited for metal surface treatment, this organic acid effectively removes rust and scale by forming water-soluble complexes with iron ions. Its dihydrate form offers stable handling and precise solubility. Alliance Chemical supplies this material in sizes ranging from lab-scale quantities to bulk 55 lb bags to support diverse operational needs.
