2,6-Dimethylaniline, also known as 2,6-xylidine, is a chemical intermediate with a well-defined set of physical and chemical properties that dictate its handling and application. Understanding these characteristics is crucial for ensuring safe and effective use in industrial and laboratory settings. This article provides an in-depth look at the properties of 2,6-dimethylaniline and outlines important safety considerations.

Physically, 2,6-dimethylaniline presents as a colorless to light yellow liquid. It has a relatively high boiling point of approximately 217.9°C and a melting point in the range of 10-12°C, classifying it as a liquid at typical room temperatures. Its density is around 1.0 g/cm³, and it is slightly soluble in water (7.5 g/L at 20°C) but readily soluble in organic solvents like ethanol and diethyl ether. The compound's exact mass is 121.180, with a molecular formula of C8H11N.

Chemically, 2,6-dimethylaniline is an aromatic amine. It is stable under recommended storage conditions but is noted to be sensitive to air and light. Key chemical properties include its basicity, indicated by a pKa of 3.89. It can react with strong oxidizing agents and acids, necessitating careful consideration of incompatible materials during storage and processing. Its flash point is approximately 91.1°C, classifying it as a combustible liquid.

Safety is a paramount concern when working with 2,6-dimethylaniline. The compound is classified as harmful if swallowed, inhaled, or absorbed through the skin. It can cause skin irritation and may cause respiratory irritation. Furthermore, it is suspected of causing cancer (IARC Group 2B). Proper personal protective equipment (PPE), including gloves, eye protection, and respiratory protection in well-ventilated areas, is essential. Storage should be in a cool, dry place, with containers tightly closed, away from sources of ignition and incompatible substances.
