Ethylenediaminetetraacetic acid tripotassium/EDTA tripotassium 65501-24-8
Category : Others
CAS NO : EC NO : MF : C10H17K3N2O10 MW : 442.5443 Specification : White Powder Packing : 500g/bottle Product description : EDTA tripotassium, also known as ethylenediaminetetraacetic acid tripotassium, abbreviated as EDTA-K3, is a chemical substance and a chemical raw material with a CAS of 65501-24-8. It is a white crystalline powder, odorless, easily soluble in water, hygroscopic, and has a molecular weight of 442.56. It is often used as a blood anticoagulant and added to vacuum tubes for pre-treatment of blood samples in blood collection and testing. EDTA tripotassium performance 1. The molecular weight is 442.56, and the pH value is between 7.3 ± 1 in a 5% aqueous solution. The solubility in water is ≥ 60% at 25 ° C and is stable at room temperature. 2. With a purity of over 99% and no impurities, after powder dissolution, the water has a high clarity visible to the naked eye, making it easy to add to the blood collection vessel without any other adverse effects. 3. EDTA tripotassium has no damage to blood cells and does not interfere with the size of white blood cell counts, preventing platelet aggregation, making it suitable for general hematological examinations. However, it should be noted that due to its anticoagulant effect, it is not suitable for coagulation testing experiments. In addition, the ability to chelate calcium ions is also not suitable for the determination of calcium ions, sodium ions, iron ions, etc. Uses : Blood collection additive Synonyms : EDTA-3K·2H2O;Ethylenediaminetetraacetic acidtripotassium salt dihydrate;Ethylenediaminetetraacetic acid tripotassium salt dihydrate;tripotassium 2,2'-({2-[(carboxylatomethyl)(carboxymethyl)amino]ethyl}imino)diacetate dihydrate;EDTA tripotassium salt;EDTA-3K•2H2O; Molecular Structure :
