| Message: | EDTA-2K is a common complexing agent, which is white crystal powder. Because it can complex with calcium in blood to inactivate calcium and further lead to blood non coagulation, it is usually used to prepare anticoagulants, mainly used in the blood collection industry.
EDTA has two CAS numbers, mainly because one of them is actually potassium EDTA crystal hydrate. People often mistake the CAS numbers of these two kinds of EDTA, which makes people confused. The real situation is that the CAS number of EDTA-2K is 2001-94-7, and the CAS number of EDTA-2K dihydrate is 25102-12-9. The difference between them is that one molecule is two crystal water. This paper introduces the wide application of EDTA-2K.
The international blood Standards Committee recommends the use of EDTA-2K anticoagulant for whole blood cell count. EDTA-2K can be used as anticoagulant in vacuum blood collection to preserve leukocyte proliferation in a short time, prevent platelet aggregation and preserve platelets. In addition to being used as anticoagulant, EDTA-2K has many uses in industrial production, environmental optimization and other fields. |
