In the realm of chemical manufacturing and application, a thorough understanding of a compound's properties is fundamental to its safe and effective use. 4-Ethoxyaniline, also known as p-phenetidine, is a versatile chemical intermediate with specific characteristics that dictate its handling, storage, and application. Possessing a molecular formula of C8H11NO and a molecular weight of approximately 137.18 g/mol, it is typically described as a colorless to light yellow liquid.

One of the key properties of 4-ethoxyaniline is its sensitivity to environmental factors. It is noted to be sensitive to light and air, which can cause it to gradually turn reddish-brown upon prolonged exposure. This sensitivity is a critical consideration for its storage. To maintain its quality and purity, it is recommended to store 4-ethoxyaniline in well-closed containers, protected from light and air. Maintaining a cool, dry, and well-ventilated storage environment, often at temperatures between 2-8°C, is crucial. Furthermore, it should be stored separately from incompatible materials, such as strong oxidizing agents, to prevent hazardous reactions.

The physical parameters of 4-ethoxyaniline include a boiling point of approximately 250-255°C (lit.) and a melting point of 2-5°C (lit.). Its density is around 1.065 g/mL at 25°C. While practically insoluble in water, it exhibits solubility in organic solvents like ethanol and ether, which is typical for compounds of its chemical nature and useful for formulation purposes.

Safety is a paramount concern when working with any chemical, and 4-ethoxyaniline is no exception. It is classified as toxic by inhalation, skin contact, and if swallowed, and carries a warning for potential cumulative effects and possible irreversible effects. Proper personal protective equipment (PPE), including suitable protective clothing, gloves, and eye protection, is essential when handling this compound. In case of exposure or accidental ingestion, immediate medical attention is advised, and the product label should be readily available. The risk codes associated with it, such as R23/24/25 (Toxic by inhalation, in contact with skin and if swallowed), R33 (Danger of cumulative effects), and R68 (Possible risk of irreversible effects), highlight the need for stringent safety measures.
