Bulk Price of 3-(Diethylamino)Propylamine CAS 104-78-9 in 2026: A B2B Sourcing Guide
- Global bulk pricing for N,N-Diethyl-1,3-propanediamine varies significantly based on purity, volume, and supply chain reliability—ranging from $35/L to over $795/kg for research-grade samples.
- NINGBO INNO PHARMCHEM CO.,LTD. offers industrial-scale quantities of 3-(Diethylamino)propylamine with full COA documentation, optimized for epoxy resin formulators seeking drop-in replacements.
- Key cost drivers include packaging type, minimum order quantity (MOQ), air sensitivity handling, and compliance with GHS safety standards for this miscible, alkaline liquid.
In the evolving landscape of fine chemical procurement, buyers sourcing N,N-Diethyl-1,3-propanediamine (CAS 104-78-9)—also known as 3-(Diethylamino)propylamine or N1,N1-Diethylpropane-1,3-diamine—must navigate volatile pricing structures influenced by scale, purity, and regional logistics. As a versatile advanced organic synthesis intermediate, this diamine is widely employed in epoxy curing agents, surfactants, chelating resins, and pharmaceutical scaffolds. With 2026 market data indicating wide price dispersion—from $10 for 5 mL lab vials to $795.80 per 500 mg in ultra-high-purity research formats—industrial users require strategic insight to secure cost-efficient, reliable supply.
Understanding the True Cost Drivers Behind Bulk Pricing
The apparent discrepancy in published prices stems largely from application context. Small-volume vendors often serve R&D markets with premium markups, while certified global manufacturers like NINGBO INNO PHARMCHEM CO.,LTD. focus on tonnage-scale production with tiered commercial pricing. For instance, Sigma-Aldrich lists 2L drums at $253 (≈$126.50/L), whereas TCI Chemical offers 500 mL at $50 (≈$100/L)—both ≥99% purity. However, these catalog prices rarely reflect true bulk economics available under annual supply agreements.
Critical factors affecting final landed cost include:
- Minimum Order Quantity (MOQ): Industrial buyers typically engage at 25 kg, 200 kg, or ISO tank levels, unlocking significant per-kilogram savings.
- Packaging & Hazmat Compliance: Due to its ammoniacal odor, flash point of 138°F, and air sensitivity, this compound requires nitrogen-purged HDPE drums or IBC totes—adding logistics complexity.
- Quality Documentation: When sourcing high-purity COA-backed material for regulated applications, analytical validation (GC, NMR, water content) is non-negotiable.
Technical Profile & Formulation Relevance
With a molecular formula of C7H18N2 and MW of 130.23, 3-Aminopropyldiethylamine exhibits high water solubility (miscible), a pKa of ~10.32, and a boiling point of 169–171°C. Its bifunctional amine structure—featuring one primary and one tertiary amine—enables dual reactivity, making it ideal for:
- Epoxy resin curing (accelerated room-temperature systems)
- Synthesis of cationic surfactants and corrosion inhibitors
- Chelating ligands in metal extraction processes
- Building blocks for agrochemicals and APIs
Formulators seeking a drop-in replacement for legacy amines must verify compatibility with existing resin matrices. NINGBO INNO PHARMCHEM CO.,LTD. provides comprehensive technical dossiers and small-batch samples to validate performance equivalence before scaling.
2026 Global Bulk Pricing Benchmarks (Industrial Scale)
Based on aggregated market intelligence and verified supplier quotations, the following table outlines realistic bulk price ranges for ≥99% pure N,N-Diethyl-1,3-propanediamine under FOB China terms for qualified B2B buyers:
| Order Volume | Typical Packaging | Price Range (USD/kg) | Lead Time |
|---|---|---|---|
| 25–100 kg | 25 kg HDPE drums (N2-purged) | $18 – $28 | 2–3 weeks |
| 200–500 kg | 200 L steel drums or IBC totes | $14 – $20 | 3–4 weeks |
| 1,000+ kg | ISO tank or flexitank | $10 – $16 | 4–6 weeks |
Note: Prices exclude freight, insurance, and import duties. All shipments comply with GHS labeling and include full safety data sheets (SDS). Long-term contracts may further reduce costs through fixed-price mechanisms.
