Description

N1-Ethyl-N3-Isopropyl-1,3-Propanediamine is a versatile aliphatic diamine featuring both ethyl and isopropyl substituents on its nitrogen atoms. This unique asymmetric structure makes it a valuable intermediate for synthesizing specialized polymers, corrosion inhibitors, and pharmaceutical compounds. It is particularly sought after by manufacturers in the agrochemical, polymer, and specialty chemical industries for its bifunctional reactivity and ability to impart specific properties to final products.

Application

• Polymer & Resin Intermediate: Used in the synthesis of polyamides, polyurethanes, and epoxy curing agents, where it modifies flexibility, adhesion, and chemical resistance.
• Corrosion Inhibitor Precursor: Serves as a key building block for formulating high-performance corrosion inhibitors used in fuel additives, metalworking fluids, and industrial water treatment.
• Agrochemical Synthesis: Acts as an intermediate in the production of herbicides, fungicides, and plant growth regulators.
• Pharmaceutical Intermediate: Employed in the research and development of active pharmaceutical ingredients (APIs), particularly in molecules requiring a specific diamine backbone.
• Chelating Agent & Surfactant: Utilized to create chelating agents for metal ion control and as a component in specialty surfactants and emulsifiers.
• Crosslinking Agent: Functions as a crosslinker in coatings, adhesives, and sealants to enhance thermal stability and mechanical strength.

Quality Control

Our N1-Ethyl-N3-Isopropyl-1,3-Propanediamine is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay and impurity profile determination by GC or HPLC, to ensure high purity and consistency. Certificates of Analysis (COA) documenting all critical specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture and carbon dioxide, which can lead to degradation.
