How does it work

As an extracorporeal anticoagulant, SODIUM CITRATE 4% W/V ANTICOAGULANT SOLUTION USP binds free calcium from the blood. In the clotting cascade, calcium plays an important role in several steps. Citric acid, which regulates pH, is one of the key components of the solution.

Applications. Or where it is used

Trisodium citrate dihydrate is widely used as a buffer, sequestering agent, or emulsifier in foods and beverages. As a white, granular crystal or as a white, crystalline powder, trisodium citrate dihydrate has a pleasant, salty taste.

 Manufacturing process

A tribasic salt of citric acid, trisodium citrate belongs to the family of salts. After neutralizing citric acid with high purity sodium hydroxide or carbonate, it is crystallised and dehydrated. 

 How to use:

Citric acid is neutralised with sodium hydroxide or carbonate, and then crystallized. Food, beverage, and technical applications commonly use trisodium citrate dihydrate as a buffer, sequestering, or emulsifying agent.
