In the realm of fine chemicals, certain compounds stand out due to their versatility and critical role in various industrial synthesis processes. P-Phenetidine, known by its CAS number 156-43-4, is one such compound. Characterized as 4-ethoxyaniline, it serves as a fundamental building block across sectors like pharmaceuticals, dyes, and agrochemicals. This article aims to provide a comprehensive overview of P-Phenetidine, covering its essential properties, wide-ranging applications, and guidance on sourcing from reputable chemical manufacturers and suppliers.

Chemical Profile of P-Phenetidine: P-Phenetidine is a transparent liquid, typically appearing light yellow to reddish-brown. Its molecular formula is C8H11NO, and it has a molar mass of approximately 137.18 g/mol. A key characteristic is its sensitivity to air and light, which can lead to discoloration over time. This necessitates proper handling and storage, usually in tightly sealed containers away from light. Reputable suppliers ensure that P-Phenetidine is packaged to maintain its quality and purity, often exceeding 99% assay, which is crucial for its downstream applications.

Diverse Applications Across Industries: The versatility of P-Phenetidine makes it a sought-after intermediate. In the pharmaceutical industry, it is used in the synthesis of active pharmaceutical ingredients (APIs), contributing essential structural motifs to various drug molecules. For the dye industry, P-Phenetidine is a key precursor for azo dyes and other colorants, influencing the shade, intensity, and stability of the final product. Furthermore, in the agrochemical sector, it functions as an important intermediate in the production of pesticides and herbicides, enhancing crop protection and agricultural yields. Its utility extends to the synthesis of specialty organic chemicals, demonstrating its broad industrial relevance.

Choosing the Right Supplier: When you decide to buy P-Phenetidine, selecting the right manufacturer and supplier is critical. Look for companies that provide detailed Certificates of Analysis (CoA) confirming purity and specifying impurity profiles. A reliable supplier will also offer a robust Safety Data Sheet (SDS) with handling and safety information. Manufacturers in China, offering competitive pricing and large-scale production capabilities, are often key players in the global supply chain. Ensure the supplier has a proven track record of quality and timely delivery, especially for bulk orders.

Market Insights and Future Trends: The demand for P-Phenetidine is closely tied to the growth of its end-use industries. As pharmaceutical research and development continues to advance, and as the need for innovative agrochemicals and high-performance dyes persists, the market for P-Phenetidine is expected to remain strong. Manufacturers are continually optimizing production processes to ensure high purity and cost-effectiveness, making it an attractive intermediate for a wide range of applications.

Conclusion: P-Phenetidine (CAS 156-43-4) is a fundamental intermediate with broad applications across major industrial sectors. Its inherent chemical properties, coupled with the availability of high-purity material from dedicated manufacturers, solidify its position as a key raw material. For companies looking to purchase P-Phenetidine, a focus on quality, reliability, and competitive pricing from experienced suppliers will ensure successful integration into their production processes.
