Uses: biochemical research. EGTA is the most widely used calcium ion selective chelating agent. Its complex with calcium ions is 100,000 times more stable than the complex with magnesium ions, and is used to prepare calcium buffers and control the concentration of calcium ions. Measure complexing agents and masking agents of trace metals in volume analysis and photometric analysis. Barium, strontium, copper, magnesium and zinc can also be titrated. Storage: RT
