For businesses in the pharmaceutical, dye, and agrochemical sectors, securing a reliable supply of high-quality P-Phenetidine (CAS 156-43-4) is paramount. As a specialized manufacturer, understanding the critical factors for quality assurance is key to successful procurement. This article outlines what buyers should look for when sourcing this vital chemical intermediate.

Understanding P-Phenetidine's Properties: P-Phenetidine, identified by CAS number 156-43-4, is typically a light yellow to reddish-brown transparent liquid. Its molecular formula is C8H11NO, with a molar mass of 137.18 g/mol. While stable under recommended storage conditions, it is noted to be sensitive to air and light, often turning red or brown upon prolonged exposure. This sensitivity underscores the importance of proper packaging and handling by both the manufacturer and the end-user.

Key Specifications for Pharmaceutical and Dye Applications: When you buy P-Phenetidine for pharmaceutical synthesis or dye production, purity is non-negotiable. Most reputable suppliers, including us, offer P-Phenetidine with an assay of 99% or higher. Critical impurities to monitor include related aniline compounds and residual solvents. Certificates of Analysis (CoA) from the manufacturer are indispensable, detailing not just the assay but also specific impurity profiles, density, and refractive index. These specifications ensure the P-Phenetidine will perform as expected in complex reaction pathways.

The Role of a Reliable Manufacturer: Partnering with an established manufacturer in China offers significant advantages. Firstly, it ensures direct access to a consistent supply chain and competitive pricing. Secondly, experienced manufacturers have robust quality control systems in place, from raw material sourcing to final product testing. This diligence minimizes risks associated with product variability. When seeking a supplier, inquire about their production capacity, adherence to international quality standards, and their experience in exporting chemical intermediates.

Evaluating Potential Suppliers: Beyond the CoA, consider a supplier's transparency and technical support. A responsive supplier who can provide detailed technical data sheets (TDS) and safety data sheets (SDS) is invaluable. For bulk purchases, negotiating terms, minimum order quantities (MOQ), and lead times is crucial. For those looking to buy P-Phenetidine, a site visit or audit of the manufacturing facility can further build confidence in the supplier's capabilities and commitment to quality.

Conclusion: Sourcing P-Phenetidine effectively requires a thorough understanding of its properties and a discerning approach to supplier selection. By focusing on purity, seeking detailed specifications, and partnering with a reliable manufacturer, businesses can ensure the quality and consistency needed to drive innovation in their respective industries. If you are looking to purchase P-Phenetidine, reach out to experienced manufacturers to discuss your specific requirements.
