Product Overview
Ethylenediaminetetraacetic acid (EDTA) disodium salt dihydrate is a high-purity chelating agent designed for precision in analytical and biochemical applications. With a minimum purity of 99%, this lab-grade compound effectively binds metal ions, preventing interference in sensitive reactions. Its dihydrate form ensures stability and solubility in aqueous solutions, making it ideal for water softening, enzymatic studies, and buffer preparations. The white crystalline powder dissolves readily, providing consistent performance in titration, complexometry, and molecular biology protocols. As a disodium salt, it offers balanced pH compatibility, reducing the need for additional adjustments. The compound’s strong chelation properties make it indispensable in preventing metal-catalyzed oxidation, ensuring reliable results in research and industrial testing. Store in a cool, dry place to maintain its integrity and extend shelf life.
FAQs
1. What is the solubility of EDTA disodium salt dihydrate in water?
It is highly soluble in water, typically dissolving at concentrations up to 100 mg/mL, depending on temperature and pH conditions.
2. Can this EDTA salt be used for cell culture applications?
While primarily used in analytical chemistry, it can be employed in cell culture for metal ion sequestration, but compatibility should be verified for specific cell lines.
3. How does this compare to EDTA tetrasodium salt?
EDTA disodium salt has a lower pH in solution compared to the tetrasodium form, making it more suitable for applications requiring neutral to slightly acidic conditions.
4. What is the recommended storage condition for long-term stability?
Store in an airtight container at room temperature, away from moisture and direct sunlight, to prevent degradation and clumping.
5. Is this product suitable for preparing EDTA solutions for DNA extraction?
Yes, its high purity and chelating efficiency make it ideal for DNA extraction buffers to inhibit metal-dependent nucleases.
