For chemists, researchers, and manufacturers working with chemical intermediates, a thorough understanding of their properties is fundamental. 2,6-Dimethylaniline, identified by CAS number 87-62-7 and often referred to as 2,6-Xylidine, is a primary aromatic amine with distinct characteristics that dictate its applications and handling requirements. This exploration delves into its key chemical and physical properties, safety considerations, and storage best practices.

Chemically, 2,6-Dimethylaniline has the molecular formula C8H11N and a molecular weight of 121.18 g/mol. It is a derivative of aniline, with two methyl groups positioned ortho to the amino group. This structural feature influences its reactivity, making it a valuable intermediate in organic synthesis. Its physical appearance is typically described as a colorless to reddish-yellow liquid, though slight variations can occur depending on purity and storage conditions.

Key physical properties include a boiling point of approximately 216-217 °C at atmospheric pressure and a melting point around 10-12 °C. Its density is close to 0.984 g/mL at 25 °C, and it exhibits limited solubility in water, with about 13 g/L at 20 °C, but is soluble in many organic solvents. The flash point of 2,6-Dimethylaniline is around 91 °C, classifying it as a combustible liquid.

From a safety perspective, 2,6-Dimethylaniline is classified as harmful if swallowed, inhaled, or in contact with skin. It can cause skin irritation and may cause respiratory irritation. Importantly, it is also listed as suspected of causing cancer and is toxic to aquatic life with long-lasting effects. Therefore, proper handling procedures are essential. This includes working in well-ventilated areas, using appropriate personal protective equipment (PPE) such as gloves, eye protection, and respiratory masks, and avoiding release into the environment.

Storage recommendations for 2,6-Dimethylaniline typically involve keeping it in tightly closed containers in a cool, dry, and well-ventilated place, away from sources of ignition and incompatible materials like strong oxidizing agents and acids. Adherence to these guidelines ensures product stability and safety during storage. For reliable sourcing of high-quality 2,6-Dimethylaniline, partnering with experienced chemical manufacturers and suppliers, such as NINGBO INNO PHARMCHEM CO.,LTD., is recommended. They can provide comprehensive safety data sheets (SDS) and ensure the chemical is handled and transported according to all regulations.
