Chemical Structure
Basic Chemical Info
CAS 52338-87-1 functions as a highly specialized, dual-action tertiary amine catalyst and polyurethane curing agent. Structurally, it features a central urea core symmetrically flanked by two 3-(dimethylamino)propyl chains. This precise molecular architecture makes it exceptionally effective at balancing blowing and gelling dynamics in flexible or rigid foam systems.

FAQ
Q1: Can your CAS 52338-87-1 replace traditional volatile amine catalysts like BDMAEE or TEDA?
Yes. It is widely used to replace or blend with traditional volatile catalysts. Because it binds directly into the polymer network, it significantly reduces total volatile organic emissions (VOCs) without compromising demold times.
Q2: What are the optimal storage conditions to maximize shelf life?
We recommend storing the product in its original, unopened packaging between 2°C and 8°C, or in a cool, dry, well-ventilated warehouse away from strong acids and oxidizers. Keeping a dry nitrogen blanket over opened containers prevents moisture absorption.
Q3: Do you support trial orders for manufacturing pilot runs?
Yes. While our standard industrial packing unit is 25kg, we provide smaller, certified evaluation samples for quality testing and initial pilot line validation.
Introduction to N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine
Antioxidant 6PPD (CAS No. 793-24-8), chemically identified as N-(1,3-dimethylbutyl)-N‘-phenyl-p-phenylenediamine (also designated as Antioxidant 4020), stands as the undisputed global benchmark among p-phenylenediamine (PPD) anti-ozonants. It provides exceptional, multi-functional defense against ozone degradation, thermal oxidation, and flex-cracking in both natural and synthetic rubber matrices.
As a premier, fully integrated rubber chemicals manufacturing plant and direct B2B supplier, we control the entire synthesis loop from feedstock pre-treatment to final pastillation. This technical brief details our production engineering, operational scale, and cross-border chemical supply chain integrity.
Advanced Production Technology
Our manufacturing plant synthesizes CAS 52338-87-1 through a streamlined, eco-friendly condensation route. High-purity N,N-dimethyl-1,3-diaminopropane reacts directly with refined urea under precise thermodynamic reflux conditions.
- Advanced Ammonia Stripping: Throughout the reaction, automated nitrogen sparging continuously removes ammonia gas, driving the synthesis equilibrium to maximum yield while minimizing incomplete side reactions.
- High-Vacuum Fractional Distillation: The crude reaction mixture is passed through a multi-stage vacuum fractionation column. This precise engineering step effectively removes unreacted primary amines, lowering residual odor and yielding a high-purity final product.
Competitive Product Advantages
Compared to standard tertiary amine catalysts on the market, our factory-refined CAS 52338-87-1 offers clear operational advantages for your production lines:
- Reactive Immobilization: Because it contains active urea hydrogens, this molecule chemically binds directly into the polyurethane polymer matrix during cross-linking. This prevents catalyst migration, resolving issues with fogging or amine odors in automotive interiors.
- Excellent Viscosity Stability: Our synthesis process eliminates trace moisture and metallic salts, preventing premature gelation or product separation during long-term storage in pre-blend polyol systems.
- Balanced Catalytic Profiles: It provides smooth, synchronous control over both water-isocyanate (blowing) and polyol-isocyanate (gelling) pathways, eliminating the need to blend multiple expensive catalysts.
Factory Capacity & Global Compliance
Choosing us as your primary supplier ensures a resilient, highly compliant supply chain for your manufacturing needs:
- High Volume Scalability: Our specialized chemical synthesis workshop yields over 300 metric tons annually, guaranteeing reliable, continuous bulk shipping even during seasonal market spikes.
