Product Overview
DIETHYLENE TRIAMINE PENTA ACETIC ACID (DTPA) 99% is a high-purity chelating agent designed for synthesis applications, offering exceptional metal-binding efficiency. This white, crystalline powder forms stable complexes with a wide range of metal ions, making it indispensable in analytical chemistry, environmental testing, and industrial processes. Its high solubility in water and resistance to hydrolysis ensure reliable performance in demanding lab conditions. The synthesis-grade purity guarantees minimal impurities, reducing interference in sensitive experiments. DTPA’s pentadentate structure enables strong coordination with transition metals, alkaline earths, and lanthanides, providing superior selectivity compared to EDTA. Whether used for titrations, sequestration, or as a masking agent, this reagent delivers consistent results. The fine particle size ensures rapid dissolution, while the anhydrous form prevents moisture-related degradation. Compatible with most aqueous and organic solvents, DTPA 99% maintains stability across a broad pH range, enhancing its versatility in complex formulations. Store in a cool, dry place to preserve its chelating properties and extend shelf life.
FAQs
1. What is the primary function of DTPA 99% in lab applications?
DTPA 99% acts as a chelating agent, binding metal ions to prevent precipitation, interference, or catalytic reactions in solutions. Its high affinity for metals like iron, copper, and calcium makes it ideal for analytical and synthesis workflows.
2. Can this DTPA grade be used for environmental water testing?
Yes, the synthesis-grade purity (99%) ensures low background interference, making it suitable for trace metal analysis in environmental samples, including water, soil, and industrial effluents.
3. How does DTPA compare to EDTA in terms of metal selectivity?
DTPA forms stronger complexes with larger metal ions (e.g., lanthanides, actinides) and offers better selectivity for iron(III) and copper(II) compared to EDTA, which binds a broader range of metals with moderate affinity.
4. What solvents is DTPA 99% soluble in?
It is highly soluble in water and polar organic solvents like methanol and ethanol. Solubility in nonpolar solvents is limited, but it can be enhanced with pH adjustment or co-solvents.
5. What precautions should be taken during storage to maintain purity?
Store in an airtight container away from moisture and direct sunlight. Avoid exposure to strong oxidizing agents, as DTPA can degrade under extreme conditions. Keep the container sealed when not in use.
