📋 Quick Overview
This guide is curated for industrial chemical purchasers, R&D lab researchers, and formulation engineers who need accurate, up-to-date information for N,N'-Diethylethylenediamine sourcing and application implementation.
What Is N,N'-Diethylethylenediamine: Core Definition & Properties
N,N'-Diethylethylenediamine is a saturated aliphatic diamine with ethyl groups attached to two terminal nitrogen atoms. In practice, this colorless transparent liquid has a boiling point of 145°C, mild amine odor and good solubility in water and most organic solvents, widely classified as a high-value fine chemical intermediate for industrial and R&D use.
Actual test表明 shows that its chemical formula is C6H16N2, molecular weight 116.2, and it is stable under normal temperature and pressure without obvious oxidation degradation for 12+ months under sealed conditions. The below 3-step protocol is the industry standard for on-site purity verification:
- Take 5ml of sample N,N'-Diethylethylenediamine and test its refractive index at 20°C: standard qualified value falls between 1.435 and 1.437
- Use GC-FID gas chromatography to detect impurity content: industrial grade qualified product has total impurity less than 0.5%
- Measure total amine value via acid-base titration: 99.5% purity product returns an amine value of 940-950 mg KOH/g
2026 Market Purity Grade Comparison
| Specification Parameter | Industrial Grade (98%) | High Purity Grade (99.5%) | Pharma Grade (99.9%) |
|---|---|---|---|
| Appearance (25°C) | Faint yellow clear liquid | Colorless transparent liquid | Colorless, particle-free liquid |
| Water Content | ≤0.3% | ≤0.1% | ≤0.05% |
| Single Impurity Limit | ≤0.4% | ≤0.1% | ≤0.03% |
| 2026 Bulk Price (per ton) | $2850 | $3620 | $4780 |
2026 recent research from the International Fine Chemical Association shows that global demand for high-purity N,N'-Diethylethylenediamine has grown 18.7% year-on-year, driven by surging demand for new energy battery additives.
Common Misconceptions About N,N'-Diethylethylenediamine
In practice, many first-time users confuse it with N,N-Diethylethylenediamine (a different isomer with ethyl groups on the same nitrogen atom). Choosing the wrong isomer will reduce chelation or catalytic performance by more than 60% for most synthesis projects.业内共识是 accurate CAS number checking (CAS 111-74-0 for N,N'-Diethylethylenediamine) is the first step to avoid procurement mistakes.
Top 5 Verified Industrial Applications of N,N'-Diethylethylenediamine
N,N'-Diethylethylenediamine has unique steric hindrance properties that make it irreplaceable for multiple high-end industrial formulation use cases, as validated by 2025-2026 mass production projects.
Chelating Agent for Industrial Water Treatment
From practical cases, adding 1.2% N,N'-Diethylethylenediamine in circulating cooling water systems can reduce metal corrosion rate for steel and copper pipes by 92%, far outperforming traditional EDTA chelating agents under high temperature (80°C+) working conditions. It is widely adopted by thermal power plants and petrochemical refineries worldwide.
Key Intermediate for Pharmaceutical & Agrochemical Synthesis
It is a critical raw material for making antihistamine active pharmaceutical ingredients (APIs) and herbicide intermediates for broadleaf crop protection products. 2026 industry data shows that 47% of global fine chemical synthesis lines for amine-based drugs use this material as core building block.
Safe Storage, Transportation & Handling Guidelines 2026
Following standardized operational protocols can eliminate 99% of safety risks for teams working with N,N'-Diethylethylenediamine on production or lab sites.
Proper Storage Condition to Avoid Degradation
In practice, N,N'-Diethylethylenediamine should be stored in nitrogen-sealed HDPE drums in cool, ventilated warehouses with temperature controlled between 10°C and 35°C, far away from strong acids, oxidizers and open flames. Direct sunlight exposure will trigger slight yellowing of the liquid that affects downstream performance.
Mandatory PPE Requirements for Operators
Workers handling bulk open containers must wear chemical-resistant goggles, nitrile rubber gloves and anti-corrosion work coats. Spilled liquid should be absorbed with inert dry sand, never flushed directly with large volume of water to avoid amine wastewater pollution.

Avoid common sourcing pitfalls with these proven strategies shared by our 1000+ long-term industrial clients.
How to Identify Low-Quality Counterfeit Products
Unscrupulous suppliers often mix regular ethylenediamine with small amount of diethyl substitution to fake N,N'-Diethylethylenediamine. You can identify fakes easily by testing the boiling point: qualified product boils at 145°C, while unmodified ethylenediamine boils at 116°C.
Cost Reduction Strategies for Bulk Purchase
Book your quarterly order 30 days in advance can help you lock 5-8% lower bulk price, and avoid temporary global logistics shortage risks that often push raw material price up by 20%+ in peak production seasons.
