In the vast world of chemical intermediates, few compounds offer the versatility and broad-spectrum utility of 3-Dimethylaminopropylamine, commonly known as DMAPA. Identified by its CAS number 109-55-7, this organic compound is a cornerstone in the synthesis of a multitude of products that are integral to our daily lives. As a leading chemical innovator, NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to producing high-purity DMAPA, empowering industries from personal care to high-performance materials. This document delves into the essential properties, critical applications, and the superior quality of DMAPA supplied by our company.

Understanding 3-Dimethylaminopropylamine (DMAPA)

DMAPA, with the chemical formula C5H14N2, is a clear, colorless liquid characterized by a distinct amine-like odor. It is a unique diamine, possessing both a primary and a tertiary amine group, which is the key to its remarkable reactivity and functional versatility. This dual-functionality allows it to act as an effective building block and reactive agent in numerous chemical processes.

Key physical and chemical properties of our high-grade DMAPA include:

• Melting Point: -60 °C
• Boiling Point: 133 °C (lit.)
• Density: 0.812 g/mL at 25 °C (lit.)
• Vapor Pressure: 5 mm Hg (20 °C)
• Refractive Index: n20/D 1.435 (lit.)
• Flash Point: 90 °F - indicating it is a flammable liquid requiring appropriate handling.
• Water Solubility: Fully soluble, which simplifies its use in aqueous-based formulations and processes.
• pH: 12.7 (100g/l, H2O, 20ºC), highlighting its strong basicity.

Core Applications: A Testament to Versatility

The unique molecular structure of DMAPA makes it an indispensable ingredient across a wide array of industrial sectors. Its applications are extensive and continue to grow as new technologies emerge.

1. Surfactant Production: The Heart of Personal Care
Perhaps the most significant application of DMAPA is as a crucial intermediate in the synthesis of amphoteric surfactants. Specifically, it is the primary raw material for producing cocamidopropyl betaine (CAPB)
. CAPB is a celebrated ingredient in countless personal care products, including shampoos, body washes, liquid soaps, and facial cleansers. Its popularity stems from its exceptional mildness, excellent foam-boosting capabilities, and viscosity-building properties. Unlike harsher surfactants, those derived from DMAPA are gentle on the skin and eyes, making them ideal for products designed for daily use. NINGBO INNO PHARMCHEM CO.,LTD. is a premier manufacturer of the high-purity DMAPA required to produce these superior, skin-friendly surfactants.

2. Epoxy Resin Curing Agent
In the world of high-performance materials, DMAPA serves as a highly effective curing agent (hardener) for epoxy resins. Its two amine groups readily react with the epoxide groups of the resin, creating a strong, cross-linked, three-dimensional thermoset structure. This process imparts exceptional mechanical strength, thermal stability, chemical resistance, and adhesion to the final cured product. These properties are vital in demanding applications such as industrial coatings, high-strength adhesives, electrical encapsulations, and composite materials used in the automotive and aerospace industries. For companies seeking to purchase a reliable epoxy curing agent, our DMAPA provides consistent and predictable performance.

3. Catalyst for Polyurethanes and Other Syntheses
The tertiary amine group in DMAPA makes it an excellent catalyst, particularly in the production of polyurethane (PU) foams. It accelerates the reaction between polyols and isocyanates, ensuring uniform foam rise and proper curing. Its catalytic activity is also harnessed in various other organic syntheses, helping to improve reaction rates and yields, thereby making manufacturing processes more efficient and economical.

4. Water Treatment and Flocculants
DMAPA is used to synthesize cationic polymers that act as flocculants in water treatment processes. These polymers effectively neutralize the charge of suspended particles in wastewater, causing them to aggregate into larger flocs that can be easily filtered out. This application is critical for industrial effluent treatment and ensuring environmental compliance. As a dedicated supplier, we understand the importance of consistent quality for such critical environmental applications.
