Dipotassium EDTA, identified by CAS number 25102-12-9, is a compound that plays a significant role across various scientific and industrial sectors, most notably as a blood anticoagulant and a chelating agent. Understanding its properties, applications, and how to source it effectively is crucial for professionals in laboratory diagnostics, research, and manufacturing. As a dedicated manufacturer and supplier, we aim to provide comprehensive insights into this vital chemical.

Understanding Dipotassium EDTA's Core Properties

Dipotassium EDTA is characterized by its physical form: a white crystalline powder. It is virtually odorless and exhibits excellent solubility in water, a property that facilitates its use in aqueous solutions and biological samples. Its molecular formula, C10H14K2N2O8·2H2O, and molecular weight of approximately 404.45 g/mol, along with a typical pH range of 4.8±1 for a 5% aqueous solution, underscore its defined chemical nature. A key attribute is its chelating ability – its capacity to bind with metal ions, especially calcium, which is fundamental to its anticoagulant action.

Primary Applications: From Blood Collection to Beyond

The most recognized application of Dipotassium EDTA is its use as an additive in vacuum blood collection tubes. Its ability to chelate calcium ions effectively prevents blood coagulation, making it indispensable for:

  • Hematological Analysis: Preserving the morphology of blood cells (red blood cells, white blood cells, platelets) for accurate counts and differential analysis.
  • DNA Stabilization: Acting as a chelating agent to inactivate metal-dependent nucleases, thereby protecting DNA from degradation. This is critical for molecular diagnostic assays and research.

Beyond these primary uses, Dipotassium EDTA finds application as a complexing agent in various analytical procedures, in detergents, and as a stabilizer in cosmetic formulations, highlighting its versatility.
