Ethylenediaminetetraacetic Acid 99.5% AR Grade Reagent
Cas Number:60-00-4
Formula:C10H16N2O8
Molar Mass:292.24
EC Number:200-449-4
Physicochemical properties:
White powder. It is soluble in sodium hydroxide, sodium carbonate and ammonia solution and also soluble in 160 parts boiling water, slightly soluble in cold water, insoluble in ethanol and common organic solvents. It can form extremely stable water-soluble complexes with alkali metals, rare earth elements and transition metals. The melting point is 240 ° C (decomposition). Irritating.
Usage:
Complexing agent. Blood anticoagulant. In biochemical studies, the inhibition of heavy metals on the catalytic reaction of enzymes is eliminated. Detergent. Masking agent.
Packing:
500g/25kg
