 Calcium Dicitraconate Disodium   Detailed Information Main Uses and Applications  The core function of calcium disodium ethylenediaminetetraacetate CAS  23411-34-9 lies in its powerful ability to chelate metal ions.  Pharmaceutical field: As a heavy metal detoxifying agent, it is used to treat poisoning caused by metals such as lead, cobalt, copper, and manganese. It can combine with these heavy metal ions in the body into stable and soluble complexes, and then be excreted from the body through urine. It is also used in clinical practice to treat hypercalcemia caused by hyperfunction of the parathyroid glands.  Food Industry: Used as chelating agents, preservatives and antioxidants. By chelating the trace metal ions (such as iron and copper) in food, it can effectively prevent food from oxidizing and discoloring, deteriorating, and inhibiting the turbidity of boiled food. It is widely used in beverages, dairy products, canned and bottled foods, such as v...

  What is Diethyltoluenediamine CAS 68479-98-1 ? Diethylmethylenediamine is usually a mixture of two isomers (approximately 76% of 3,5-dioctyl-2,4-diaminotoluene and 24% of 3,5-dioctyl-2,6-diaminotoluene). This structure endows it with some key properties:  Good compatibility: It can well dissolve with polar organic solvents such as polyether and polyester polyols, which makes it easy to be processed in the formulation.  Moderate solubility: Slightly soluble in water. The solubility at 30℃ is approximately 23 grams per liter.  Stable physical properties: Its density is approximately 1.022 g/cm³, with a relatively high boiling point of around 308-310°C and a flash point exceeding 140°C. This indicates that it is relatively stable at room temperature, but it should be kept away from high temperatures and open flames.
