Basic Information

Product Description

Product Name：ETHYLENEDIAMINETETRAACETIC ACID TRIPOTASSIUM SALT DIHYDRATE

CAS No: 65501-24-8

Form: Powder

Product Application

A. Clinical Diagnostics & In Vitro Diagnostics (IVD)

Anticoagulant:​ Serves as an alternative or complementary anticoagulant for Complete Blood Count (CBC). Compared to EDTA-2K, its weakly alkaline solution may better preserve cell morphology​ and reduce platelet aggregation, offering advantages for specific hematology analyzers or specialized tests.

Component of Biochemical Reagents:​ Used as a metal ion chelator in IVD reagent kits to eliminate interference from metal ions in enzymatic assays (e.g., creatinine, triglyceride measurements).

B. Molecular Biology & Biochemistry

Nucleic Acid Extraction & Protection:​ In DNA/RNA extraction buffers, it chelates divalent metal ions like Mg²⁺, inhibiting DNase and RNase​ activity to prevent nucleic acid degradation. Its weakly alkaline environment helps maintain nucleic acid stability.

Proteomics:​ Used in protein extraction or purification buffers to inhibit metal-dependent protease activity, preventing protein degradation.

Cell Culture:​ Used in preparing Versene (EDTA solution) or trypsin-EDTA dissociation solutions. It promotes cell detachment by chelating Ca²⁺/Mg²⁺, and its weak alkalinity is gentler on cells.

C. Analytical Chemistry

Complexometric Titration:​ Used as a titrant for determining metal ions like calcium, magnesium, and zinc, particularly suitable for titrations in weakly alkaline media.

Masking Agent:​ Used to mask interfering metal ions in spectrophotometric and electrochemical analyses.

D. Industrial & Consumer Chemistry

Personal Care Products:​ Used in high-end skincare products, shampoos, and soaps as an antioxidant synergist and stabilizer to prevent metal ion-catalyzed oxidation.

Cleaning Agents:​ Used as a water softener and chelating agent in laboratory glassware cleaning solutions and industrial detergents.
