Oxalic Acid ACS Grade: Purity for Precision

Oxalic Acid, a simple dicarboxylic acid, is distinguished by its sharp, acidic taste and its crystalline form. As an ACS Grade chemical, it is certified to meet the purity standards established by the American Chemical Society, making it ideal for academic research and industrial applications where high precision is required.

Chemical Characteristics

With the molecular formula C2H2O4, Oxalic Acid is characterized by its excellent solubility in water and its ability to form strong hydrogen bonds.

Form and Solubility

In its pure state, Oxalic Acid presents as a white crystalline solid that dissolves well in water, giving off a moderately acidic solution.

Reactivity and Applications

Oxalic Acid’s efficacy as a chelating agent allows it to bind with cations like calcium and iron, making it valuable in rust removal and water treatment.

Usage and Applications

The ACS Grade Oxalic Acid has diverse applications due to its purity and reactivity.

Laboratory and Analytical Uses

In analytical chemistry, it is used as a standard for titrations and in the analysis of rare earth elements. Its role as a reducing agent in organic synthesis is also significant.

Industrial and Environmental

Its chelating properties make it useful in wastewater treatment, removing heavy metals and calcium deposits. Additionally, it’s utilized in the bleaching and cleaning of textiles and wood.

Handling and Safety

As a strong acid, Oxalic Acid ACS Grade demands respect and caution in its handling and storage.

Protective Measures

Use of gloves, safety goggles, and protective clothing is recommended. It should be handled in a well-ventilated area, and accidental contact with skin or eyes requires immediate medical attention.

Storage Guidelines

This acid should be stored in a cool, dry, and well-ventilated space, ideally in a tightly sealed container to prevent it from absorbing moisture from the air, which can lead to clumping and degradation.


Oxalic Acid ACS Grade is an invaluable component in the laboratory and industrial processes. Its ACS certification assures its quality and purity, which is essential for conducting high-level scientific research and production that demand the highest accuracy and safety standards.
