Product Name – ETHYLENE DIAMINE TETRAACETIC ACID 99.4% AR/ACS Quantity/Pack Size – 100 g, 500 g Form – White crystalline powder Grade – AR/ACS (Analytical Reagent/American Chemical Society) Application – Chelation, titration, molecular biology, water treatment

Product Overview

ETHYLENE DIAMINE TETRAACETIC ACID (EDTA) 99.4% AR/ACS is a high-purity, versatile chelating agent widely recognized for its ability to bind metal ions with exceptional stability. This analytical-grade compound ensures minimal impurities, making it ideal for applications demanding precision, such as complexometric titrations, biochemical assays, and industrial water softening. Its white crystalline form dissolves readily in water, forming stable complexes with calcium, magnesium, and transition metals, preventing interference in sensitive reactions. The AR/ACS certification guarantees compliance with stringent purity standards, ensuring reproducible results in laboratories. EDTA’s broad pH compatibility (across acidic to alkaline conditions) enhances its utility in diverse protocols, from DNA extraction buffers to detergent formulations. As a non-volatile, thermally stable compound, it maintains integrity under standard lab conditions, reducing variability in experimental outcomes. Whether used as a sequestering agent in molecular biology or a standard in volumetric analysis, this EDTA variant delivers consistent performance, backed by rigorous quality control. Store in a cool, dry place to preserve its chelating efficacy and extend shelf life.

FAQs

1. What is the solubility of EDTA 99.4% AR/ACS in water?

EDTA 99.4% AR/ACS is highly soluble in water (0.5 g/L at 20°C), forming clear, colorless solutions. Adjust pH with sodium hydroxide for complete dissolution if needed.

2. Can this EDTA grade be used for cell culture applications?

While primarily designed for analytical and industrial use, this AR/ACS-grade EDTA can be employed in cell culture for detachment protocols, provided it undergoes sterile filtration (0.22 µm) prior to use.

3. How does EDTA 99.4% AR/ACS compare to disodium EDTA?

This free-acid form of EDTA requires neutralization (e.g., with NaOH) for aqueous solutions, unlike disodium EDTA, which is pre-dissolved. It offers higher purity but demands pH adjustment for full solubility.

4. What is the typical shelf life of unopened EDTA 99.4% AR/ACS?

When stored in its original, tightly sealed container at room temperature (15–25°C), the product retains its specified purity for up to 3 years from the date of manufacture.

5. Is this EDTA suitable for environmental testing (e.g., heavy metal analysis)?h4>

Yes, its AR/ACS grade ensures low trace metal content (<5 ppm), making it appropriate for environmental sample preparation and heavy metal quantification via ICP-MS or AAS.
