Description
What is EDTA-2Na?
EDTA-2Na (C₁₀H₁₄N₂Na₂O₈·2H₂O) is a high-purity chelating agent widely used in agriculture to enhance micronutrient availability. With ≥99% reagent-grade purity, it forms stable water-soluble complexes with metal ions (Fe²⁺, Zn²⁺, Cu²⁺, Mn²⁺), preventing nutrient precipitation in soil/fertilizer systems. Its low molecular weight (372.24 g/mol) ensures rapid plant uptake.
Core Features
1. Ultra-High Purity & Performance
· Purity ≥99% (USP/EP grade): Minimal heavy metals (Pb≤5ppm, As≤2ppm) for crop safety.
· Chelation Value ≥330mg CaCO₃/g: 20% higher than industrial-grade EDTA, maximizing micronutrient delivery.
2. Optimized Physical Properties
· Appearance White crystalline powder Easy blending with solid fertilizers
· Solubility 100g/L in water (20°C) Compatible with liquid formulations
· pH Stability 4.0-10.0 range Works in diverse soil conditions
Stability & Functionality：
1. Superior Chelation Stability
· Forms 1:1 complexes with Fe/Zn/Mn/Cu (stability constants logK >14), preventing nutrient lock-up in calcareous soils (pH>7.5).
2. Fertilizer Synergy Effects
· Liquid Fertilizers: Enables 15-20% higher micronutrient loading vs. sulfates.
·Foliar Sprays: Reduces leaf burn risk (low salt index SI=12 vs. 45 for sulfates).

FAQ
Q1: Why choose EDTA-2Na over EDTA-4Na in agriculture?
A: EDTA-2Na offers better cost efficiency (30% lower dosage needed) and lower sodium content (<6.5%) to avoid soil salinization.
Q2: How does EDTA-2Na price compare to alternatives like EDDHA?
A: While 20-30% cheaper than EDDHA, EDTA-2Na is ideal for pH<7.5 soils. EDDHA is preferred for highly alkaline conditions (pH>9).
Q3: Is your EDTA-2Na suitable for organic farming?
A: Yes, when derived from plant-based precursors (certificate available). OMRI-listed for organic use in North America.
