Description

EDTA Disodium Salt Extra Pure

Primary Uses

  1. Chelating agent in titrations (complexometric analysis):
     Commonly used to determine concentrations of metal ions like calcium, magnesium, iron, and lead in water hardness and metal assays.
  2. Buffer component in molecular biology and biochemistry:
     Helps stabilize pH and protect DNA and enzymes by binding divalent metal ions (e.g., Mg²⁺, Ca²⁺) that may catalyze degradation.
  3. Water softening in analytical procedures:
     Binds with metal ions in hard water to prevent interference with chemical reactions.
  4. Preservative in biological and chemical formulations:
     Inhibits metal-catalyzed oxidation and microbial growth.

Secondary Uses

  1. Electrophoresis buffer preparation (e.g., TAE, TBE):
     Used in DNA/RNA electrophoresis to maintain ionic strength and inhibit nuclease activity.
  2. Decalcification in histology and microscopy:
     Removes calcium from tissue samples for easier sectioning and analysis.
  3. Cleaning solution additive for laboratory glassware:
     Dissolves metal deposits and scales during glassware maintenance.
  4. Stabilizing agent in enzymatic reactions:
     Prevents unwanted metal-ion-mediated side reactions.
