Monoethanolamine (MEA) ACS Grade

Product Overview

Monoethanolamine (MEA) ACS Grade (CAS 141-43-5) is a high-purity, colorless viscous liquid with a mild ammonia-like odor. Also known as Ethanolamine or 2-Aminoethanol, this bifunctional chemical compound contains both a primary amine and a primary alcohol group. This dual functionality makes it an essential component in chemical synthesis, gas scrubbing, and pH control applications.

Our ACS Grade MEA is manufactured to meet stringent quality standards, ensuring a typical assay of ≥99.0%. It is rigorously tested to strictly limit impurities such as water, iron, and heavy metals, making it suitable for ACS Reagent Grade applications and sensitive analytical processes. The material exhibits a boiling point of 170°C and is fully soluble in water and alcohols. It is packaged in robust HDPE or glass containers to maintain purity and prevent moisture absorption during storage.

Safety Precautions

Monoethanolamine is corrosive and can cause severe skin burns and eye damage. It is harmful if inhaled or swallowed. Appropriate Personal Protective Equipment (PPE), including chemical-resistant gloves, goggles, and face shields, is mandatory when handling this product. Ensure adequate ventilation or use respiratory protection to avoid inhaling vapors. Store in a cool, dry, well-ventilated area away from strong acids and oxidizers.

In the event of exposure, immediately flush eyes or skin with water for at least 15 minutes and seek medical attention. Refer to the Safety Data Sheet (SDS) for comprehensive handling and emergency procedures.
