Product Overview

Citric Acid Monohydrate 99.5-102% AR/ACS is a high-purity, water-soluble crystalline compound widely used in laboratory settings for its versatile properties. This analytical reagent (AR) and American Chemical Society (ACS) grade variant ensures minimal impurities, making it ideal for applications requiring precise pH control, such as buffer solutions, biochemical assays, and molecular biology experiments. The monohydrate form retains one water molecule per citric acid unit, enhancing stability and solubility in aqueous solutions. Its chelating ability allows it to bind metal ions, preventing interference in sensitive reactions. The powder’s fine granular consistency ensures rapid dissolution and uniform distribution in solutions. As a weak organic acid, it provides gentle acidification without the corrosive risks associated with stronger acids. The 99.5-102% purity range meets stringent lab standards, while the AR/ACS certification guarantees reliability for quantitative analyses. Store in a cool, dry place to maintain its hygroscopic stability and prevent clumping.

FAQs

1. What is the difference between Citric Acid Monohydrate and Anhydrous Citric Acid?

Citric Acid Monohydrate contains one water molecule per citric acid unit, offering better stability in humid conditions, while anhydrous citric acid lacks this water content and is more concentrated by weight.

2. Can this product be used for food-grade applications?

While this AR/ACS-grade citric acid meets high purity standards, it is specifically formulated for laboratory use and not certified for food or pharmaceutical applications.

3. How should I store Citric Acid Monohydrate to prevent degradation?

Keep the container tightly sealed in a cool, dry place away from moisture and direct sunlight to avoid hydration changes or clumping.

4. Is this citric acid suitable for preparing citrate buffers for DNA/RNA extraction?

Yes, the AR/ACS grade and high purity make it ideal for preparing citrate buffers used in nucleic acid extraction protocols.

5. What alternatives exist for pH adjustment if citric acid is unavailable?

Acetic acid or phosphoric acid can be used as alternatives, though their buffering ranges and compatibility with specific assays may differ.
