Disodium ethylenediaminetetraacetic acid dihydrate (Sigma product) related applications
Disodium ethylenediaminetraacetic acid dihydrate, produced by Sigma, is widely used in various fields. In the field of chemical analysis, it is often used as a metal ion chelating agent. Because of its unique chemical structure, it can closely chelate with a variety of metal ions to form a stable complex. In water quality testing, it can effectively complex metal ions such as calcium and magnesium in water, accurately determine the hardness of water, and make the detection results more accurate.

It is also popular in pharmaceutical preparations. In the preparation of some injections, the addition of this substance can prevent metal ions from catalyzing the oxidation and decomposition of drugs, ensure the quality and stability of drugs, prolong the shelf life of drugs, and ensure the safety and efficacy of drugs.

In industrial production, in the paint, printing and dyeing industries, it can remove metal impurities from water to avoid adverse effects on product color and quality. For example, in the fabric dyeing process, the dye can be evenly attached, the dyeing effect can be improved, and the fabric color can be more vivid and lasting.

In the food industry, it also has its own uses. It can be used as a food additive to chelate trace metal ions in food, inhibit the oxidation reaction caused by metal ions, prevent food deterioration and discoloration, prolong the shelf life of food, and maintain food flavor and quality.

All these applications demonstrate the key to the use of ethylenediaminetetraacetic acid disodium dihydrate (Sigma products) in various fields and contribute significantly to the development of many fields.
