Appearance: white crystalline powder
Solubility: solubility in water at 25ºC was 0.5g/L. Insoluble in cold water, alcohol and general organic solvents. Soluble in sodium hydroxide, sodium carbonate and ammonia solution.
Characteristics:
Ethylenediamine tetraacetic acid (EDTA) is a kind of organic compounds. It's white powder under atmospheric pressure. It is a kind of chelating agent which can act with Mg2+, Ca2+, Mn2+, Fe2+. Because most nucleic acid enzymes and the role of some protein enzymes need Mg2+, so it's often used as hibitors for nucleic acid enzyme.
Main indexes:
| Index | Standard |
| Content | ≥99.0% |
| Chloride(Cl) | ≤ 0.05% |
| Sulfate(SO4) | ≤ 0.05% |
| Heavy Metal (Pb) | ≤ 0.001% |
| Ferrum | ≤ 0.001% |
| Chelating Value | ≥ 339 |
| pH Value | 2.8-3.0 |
| Loss on Drying | ≤ 0.2% |
EDTA is an important kind of complexing agent. Application of it is very wide, it can be used for bleaching of color photographic materials in washing process, dyeing auxiliaries, fiber processing additives, cosmetic additives, blood anticoagulant, detergent, stabilizing agent, synthetic rubber polymerization initiator, EDTA is a represent material for chelating agent. it can form stable water-soluble complex with alkali metals, transition metal and rare earth element and so on. Alao it's a kind of water treatment agent and tracer agent.
We normally list 24 months as the shelf life in our COA, the real shelf life can be slightly longer than 24 months if it's stocked in good condition (drums are sealed enough, away from direct sun-light, moisture and other incompatible chemical materials).
