Pharmaceutical grade disodium edetate Disodium edetate disodium edta

Pharmaceutical grade disodium edetate Disodium edetate Chelating Agent 500 g small test disodium EDTA-2Na, also known as EDTA-2Na, is a good combination in chemistry
.

The chemical formula is C10H14N2Na2O8, the molecular weight is 336.
206, it has six coordination atoms, the complex formed is called chelate, EDTA is often used in coordination titration, generally to determine the content
of metal ions.

EDTA has important uses
in dyes, food, pharmaceuticals and other industries.

Disodium EDTA is a tasteless, odorless or slightly salty white or milky white crystalline or granular powder, odorless and odorless
.

It is soluble in water and extremely insoluble in ethanol
.

It is an important chelating agent that chelates metal ions
in solutions.

Prevents discoloration, deterioration, turbidity and oxidation loss caused by metals, and can also improve the oxidation resistance of oils and fats (trace metals such as iron and copper in oils and fats have the effect of promoting the oxidation of oils and fats
).

Feature 1.
EDTA has a wide range of coordination properties and can form stable chelates
with almost all metal ions.

Advantages: Offers a wide range of possibilities for the determination of elements (superior to acid-base, precipitation).

Disadvantages: Easy interference between multiple components - selectivity
.

2.
The coordination ratio of EDTA to the formed M-EDTA is overwhelmingly 1:1
.

3.
Most of the chelates are charged, so they can be soluble in water and react quickly
.

Toxicity protection: This product is low toxicity
.
