For procurement managers and R&D scientists in the chemical and pharmaceutical industries, securing a reliable supply of high-quality intermediates is paramount. One such crucial compound is 4-(4-hydroxyphenylazo)benzoic acid ethyl ester, identified by CAS number 4418-89-7. This article provides essential insights for buyers looking to purchase this compound, focusing on what to expect from reputable manufacturers and suppliers in China.

Understanding 4-(4-Hydroxyphenylazo)benzoic Acid Ethyl Ester
This organic compound, often described as a powder, serves as a vital chemical intermediate. Its primary utility lies in its versatile applications within organic synthesis, particularly as a precursor for creating more complex molecules. Its azo functional group and benzoic acid ester derivative structure make it valuable for developing various azo compounds, which are widely used in the dye and pigment industries. Furthermore, its potential as a building block in pharmaceutical research is increasingly recognized, offering avenues for novel drug development.

Key Considerations for Buyers
When sourcing 4-(4-hydroxyphenylazo)benzoic acid ethyl ester, several factors are critical for ensuring successful procurement. Firstly, purity is paramount. Reputable manufacturers will typically offer this chemical with a minimum purity of 97%. This level of purity is crucial for consistent results in synthesis reactions, preventing unwanted side reactions and ensuring the quality of the final product. Always confirm the specified purity and inquire about available analytical data, such as GC-MS or NMR reports, to verify quality.

Secondly, consider the supplier's credibility and track record. Manufacturers and suppliers based in China are significant players in the global chemical market. Look for companies that demonstrate a strong commitment to quality control, potentially adhering to ISO or GMP standards, especially if the intermediate is intended for pharmaceutical applications. A transparent supply chain and responsive customer service are also indicators of a reliable partner. Requesting a free sample is often a standard practice to evaluate the product's quality and the supplier's service before committing to larger orders.

Applications and Purchasing Decisions
The decision to buy 4-(4-hydroxyphenylazo)benzoic acid ethyl ester is often driven by specific project needs. For those in the dye industry, it acts as a precursor to vibrant azo dyes. In pharmaceutical research, it can be a starting point for synthesizing new active pharmaceutical ingredients (APIs) or intermediates. Understanding these applications helps procurement managers to forecast demand and select suppliers who can meet both quality and quantity requirements.

When inquiring about price, be prepared to provide details such as the required quantity, desired purity, and delivery timeline. Competitive pricing is available from Chinese manufacturers, but it's essential to balance cost with quality and reliability. Many suppliers offer flexible packaging options, from gram-scale for R&D to bulk quantities for commercial production. Planning your purchase strategically, including sample testing and supplier vetting, will ensure you procure 4-(4-hydroxyphenylazo)benzoic acid ethyl ester effectively and efficiently.

Partnering with a trusted manufacturer for your chemical intermediate needs is key to project success. Explore options from established Chinese suppliers to secure high-quality 4-(4-hydroxyphenylazo)benzoic acid ethyl ester at competitive prices.
