Description
High-Purity Oxalic Acid 99-99.5% | Industrial Cleaning Chemical
Laboratory and Industrial Grade Oxalic Acid for Multiple Applications
Oxalic Acid (C₂H₂O₄·2H₂O) is a strong dicarboxylic acid available in solid crystalline form. Offered in 99% and 99.5% purities, it is widely used across laboratory, industrial, and commercial cleaning sectors. This grade is ideal for applications in analytical chemistry, textile processing, metal surface treatment, and stain removal.
Supplied in ACS/AR and LAB grades, Oxalic Acid appears as a white, water-soluble crystalline powder. It functions as a reducing agent, rust remover, and bleaching agent, with applications ranging from laboratory reagents to cleaning formulations and pharmaceutical intermediates. For detailed chemical handling guidelines at the Occupational Safety and Health Administration.
Due to its corrosive nature, it must be handled with care and stored in a cool, dry, and well-ventilated area. It is classified under UN 3261 as a corrosive solid. For related cleaning chemicals and laboratory reagents, explore our industrial cleaning solutions .
