Product Overview

CITRIC ACID ANHYDROUS 99.5% Extra Pure is a high-purity, water-soluble organic acid widely used in laboratory settings for its consistent composition and reliable performance. This extra pure grade ensures minimal impurities, making it suitable for sensitive applications where precision is critical. The anhydrous form eliminates moisture-related variability, providing stable results in buffer solutions, pH adjustments, and as a chelating agent for metal ions. Its white crystalline powder form dissolves rapidly in water, offering excellent solubility across a broad pH range. The 99.5% purity level meets stringent lab standards, ensuring reproducibility in experimental protocols. This grade is particularly valued in biochemical research, analytical chemistry, and molecular biology for its ability to maintain solution stability without introducing contaminants. The product is packaged in airtight containers to preserve its anhydrous state and prevent hygroscopic absorption during storage.

FAQs

1. What is the difference between citric acid anhydrous and monohydrate forms?

Citric acid anhydrous contains no water molecules in its crystal structure, while the monohydrate form includes one water molecule per citric acid molecule. The anhydrous form is preferred for applications requiring precise molecular weight calculations.

2. Can this grade be used for food or pharmaceutical applications?

This product is labeled as extra pure for laboratory use only. For food or pharmaceutical applications, you would need a grade specifically certified for those industries with appropriate compliance documentation.

3. How should I store citric acid anhydrous to maintain its purity?

Store in a cool, dry place in its original tightly sealed container. Avoid exposure to moisture or humidity, as the anhydrous form can absorb water from the air, potentially altering its weight and properties.

4. What is the typical shelf life of this product when stored properly?

When stored under recommended conditions in unopened containers, citric acid anhydrous typically maintains its specified purity for 3-5 years from the date of manufacture.

5. Does this product come with a certificate of analysis?

Yes, each batch is accompanied by a certificate of analysis detailing the purity, heavy metal content, and other relevant parameters to verify its suitability for laboratory applications.
