Briefing
Richase EDTA-2Na (Disodium EDTA) delivers high purity EDTA-2Na 99% reagent grade for industrial and laboratory applications. As a versatile chelating agent in EDTA chemistry, our Na2EDTA effectively binds metal ions in processes ranging from wastewater treatment to food preservation. Available at competitive EDTA price points, this EDTA compound meets pharmacopeia standards for cosmetics and pharmaceutical uses. Ideal for analytical reagents, boiler descaling, and textile processing.
Detailed
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.
