Description

n-Methyl-n-(N,n-Dimethylaminoethyl)-Aminoethanol is a tertiary amino alcohol with bifunctional reactivity, featuring both a basic tertiary amine and a hydroxyl group in a single molecule. It serves as a high-performance catalyst and intermediate in specialty polymer synthesis, particularly for polyurethanes requiring precise reactivity control and low volatility emissions. Industrial formulators in coatings, adhesives, sealants, and elastomers rely on this compound for its balanced gelling-to-flow ratio and enhanced compatibility with aromatic isocyanates. Its molecular architecture enables superior foam stabilization and cell structure control in flexible and semi-rigid polyurethane systems.

Application

• Catalyst for flexible polyurethane slabstock and molded foams
• Intermediate in the synthesis of cationic surfactants and corrosion inhibitors
• Building block for functionalized epoxy curing agents
• Reactive modifier in waterborne polyurethane dispersions (PUDs)
• Component in high-solids industrial coatings for improved film formation
• Stabilizer in agrochemical formulations requiring pH-sensitive emulsification
• Chemical intermediate for pharmaceutical excipients (e.g., solubilizers and permeation enhancers)
• Raw material in the production of specialty quaternary ammonium compounds

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is verified for identity, assay, residual solvents, heavy metals, and water content using validated methods including HPLC, GC, IR spectroscopy, and Karl Fischer titration. Certificates of Analysis (COA) are available upon request, and manufacturing adheres to ISO 9001 and REACH-compliant practices. For customers requiring regulatory support, documentation aligning with FDA 21 CFR and EU GMP guidelines can be provided.

Storage

Preserve in a tightly closed container, protected from light. Store under inert atmosphere (nitrogen or argon) due to susceptibility to oxidation. Keep in a cool, dry place at 15–25°C. Avoid exposure to moisture and ambient air; handle in a controlled humidity environment (<30% RH) to prevent degradation from hygroscopic uptake.
