Understanding the fundamental science behind essential chemical intermediates is crucial for innovation in various industries. 4-Ethoxyaniline, commonly known as p-Phenetidine and bearing the CAS number 156-43-4, is a prime example of such a compound. NINGBO INNO PHARMCHEM CO.,LTD. is deeply involved in the production and supply of this vital organic intermediate, and we are pleased to share insights into its properties, synthesis, and the importance of reliable sourcing.

As a fine chemical, 4-Ethoxyaniline presents as a colorless liquid. Its molecular formula is C8H11NO, with a molecular weight of approximately 137.18 g/mol. This compound is characterized by an aniline ring with an ethoxy group attached at the para position. This structural arrangement imparts unique chemical characteristics that make it highly valuable in organic synthesis. While generally stable, it is noted that 4-ethoxyaniline is sensitive to air and light, often requiring storage in cool, dark, and inert conditions to maintain its purity and prevent degradation, which can manifest as a color change to red or brown.

The synthesis of 4-ethoxyaniline typically involves a series of well-established chemical reactions. Common routes might begin with p-nitrophenol or p-nitrophenetole, followed by reduction processes to convert the nitro group to an amine. For example, reacting 4-nitrophenetole with a reducing agent like hydrogen gas in the presence of a catalyst, or using chemical reducing agents such as iron in acidic media, can yield 4-ethoxyaniline. The efficiency and purity of these 4-ethoxyaniline synthesis processes are critical for producing a high-quality product suitable for downstream applications. Companies looking to buy 4-ethoxyaniline online must ensure their suppliers adhere to robust manufacturing practices.

The utility of 4-ethoxyaniline extends across several industrial sectors. Its primary applications lie in the synthesis of dyes, where it acts as a key diazo component, and in the agrochemical industry, serving as a building block for active ingredients. The p-phenetidine applications are diverse, leveraging its reactive amino group for diazotization, coupling reactions, and as a nucleophile in various organic transformations. Understanding these diverse uses is essential for chemists and formulators.
