Ethylenediaminetetraacetic acid (EDTA)

EDTA, AR 99.5%, CAS : 60-00-4 

EDTA, which stands for ethylenediaminetetraacetic acid, is a versatile chemical compound widely used in chemistry and various industries. It is a chelating agent, meaning it forms stable complexes with metal ions.

From a chemical perspective, EDTA has a unique structure with four carboxylic acid groups and two amine groups. This arrangement allows it to bind to metal ions through coordination bonds, forming stable complexes that prevent the metal ions from participating in chemical reactions.

EDTA finds applications in several fields. In analytical chemistry, it is used to determine metal ion concentrations through complexometric titrations. It forms colored complexes with metal ions, allowing for their quantification.

In the pharmaceutical and medical industries, EDTA is used as a chelating agent in treatments for heavy metal poisoning. It can bind to toxic metal ions like lead or mercury, facilitating their excretion from the body.

EDTA also plays a crucial role in the food and beverage industry, where it acts as a preservative by chelating metal ions that catalyze oxidation reactions.

From a safety perspective, EDTA is generally considered safe for use in appropriate concentrations but should be handled with care as it can be irritating to the skin and eyes.

 EDTA，代表乙二胺四乙酸，是一種廣泛應用於化學和各行業的多功能化合物。 它是一種螯合劑，這意味著它與金屬離子形成穩定的複合物。

從化學角度來看，EDTA具有獨特的結構，具有四個羧酸基和兩個胺基。 這種排列使其能夠透過配位鍵與金屬離子結合，形成穩定的絡合物，防止金屬離子參與化學反應。 

EDTA 在多個領域都有應用。 在分析化學中，它用於透過絡合滴定來測定金屬離子濃度。 它與金屬離子形成有色絡合物，從而可以對其進行定量。

在製藥和醫療行業，EDTA 用作治療重金屬中毒的螯合劑。 它可以與鉛或汞等有毒金屬離子結合，促進它們從體內排出。

EDTA 在食品和飲料行業中也發揮著至關重要的作用，它透過螯合催化氧化反應的金屬離子來充當防腐劑。

從安全角度來看，通常認為適當濃度的 EDTA 可以安全使用，但應小心處理，因為它會刺激皮膚和眼睛。 總體而言，EDTA 是一種有價值的化學化合物，可應用於分析化學、醫藥、食品保鮮以及其他需要螯合金屬離子的產業。
