For professionals in the chemical industry, a thorough understanding of the materials they handle is paramount, not only for effective application but also for ensuring safety. 4-Methylmorpholine, identified by its CAS number 109-02-4, is a compound that requires such careful consideration. While its primary applications are found in areas like electronic chemicals and organic synthesis, its inherent properties and associated hazards are critical pieces of information for any B2B purchaser or handler.

Key Physical and Chemical Properties

4-Methylmorpholine, also commonly known as N-Methylmorpholine, presents itself as a clear liquid. Its molecular formula is C5H11NO, and it possesses a molecular weight of approximately 101.15 g/mol. Important physical parameters include:

  • Appearance: Clear Liquid
  • Boiling Point: Approximately 114.1 °C at 760 mmHg.
  • Flash Point: Approximately 23.9 °C. This low flash point classifies it as a flammable liquid, demanding careful storage and handling away from ignition sources.
  • Density: Approximately 0.931 g/cm³.
  • Solubility: It is noted to be soluble.

These properties are vital for chemists and formulators when determining its suitability for specific reactions or formulations, especially in sensitive applications such as photoresist chemicals.

Safety Information and Hazard Symbols

The handling and transportation of 4-Methylmorpholine are governed by strict safety protocols, due to its classification as a hazardous substance. The compound is typically marked with hazard symbols that indicate its risks. Common hazard symbols associated with it include 'C' (Corrosive) and 'F' (Flammable). These symbols serve as immediate warnings:

  • Flammability (F): The low flash point means that vapors can easily ignite, posing a fire risk. Proper ventilation and avoidance of open flames or sparks are essential.
  • Corrosivity (C): This suggests that the chemical can cause damage to skin, eyes, and certain materials. Appropriate personal protective equipment (PPE), such as chemical-resistant gloves, eye protection, and protective clothing, is mandatory when handling 4-Methylmorpholine.

For any business looking to buy 4-Methylmorpholine, obtaining and thoroughly reviewing the Material Safety Data Sheet (MSDS) from the manufacturer or supplier is a non-negotiable step. This document provides comprehensive information on hazards, safe handling procedures, emergency measures, and disposal guidelines.

Sourcing Reliable 4-Methylmorpholine

When procuring 4-Methylmorpholine (CAS 109-02-4), whether for research or industrial scale, it is crucial to source from reputable manufacturers and suppliers, particularly those in China known for their adherence to quality and safety standards. Understanding these properties and hazards empowers you to make informed decisions and ensure safe, efficient use of this important chemical intermediate.
