Description

Ethylmethylamine (CAS 624-78-2 ), also referred to as N-methylethylamine, is a secondary aliphatic amine used as a reactive building block and process chemical across pharmaceutical, personal care, and specialty chemical manufacturing. Its secondary amine functionality makes it a practical intermediate for synthesizing active compounds and functional additives. In pharmaceutical synthesis, it serves as an alkylating agent or amine source in the preparation of API intermediates. This chemical is essential where controlled reactivity and defined nitrogen substitution are required. Personal care formulators use it in the development of conditioning agents and buffering components where pH management is critical. In flavor chemistry, it contributes to the construction of nitrogen-containing aroma compounds targeting specific taste profiles. It also finds use as a curing agent or crosslinker in specialty resin and coating formulations. These applications require secondary amine reactivity to ensure product stability and performance. Ethylmethylamine is supplied as a liquid, typically in bulk drums or isotanks suited for industrial quantities. Technical grade is the standard commercial offering, with high-purity grades available for pharmaceutical and flavor applications. Buyers should confirm concentration and stabilizer content with suppliers before purchase. The product is often handled under inert conditions due to its volatility and reactive nature. Ensuring proper storage and handling protocols is vital for maintaining the integrity of the chemical during transport. Contact us for supply of Ethylmethylamine Request Quote
