For businesses in the pharmaceutical, dye, and agrochemical sectors, securing a reliable supply of high-quality 4-Aminophenol (CAS 123-30-8) is paramount. As a key intermediate, its purity and consistency directly impact the efficacy and safety of downstream products. This guide is designed for B2B procurement managers and R&D scientists seeking to understand the critical factors when sourcing this essential fine chemical, with a specific focus on finding competitive prices and dependable manufacturers in China.

Understanding 4-Aminophenol: Applications and Quality Standards

4-Aminophenol is a versatile organic compound with a molecular formula of C6H7NO. Its significance lies in its role as an intermediate for a wide array of products. The most well-known application is in the synthesis of paracetamol (acetaminophen), a widely used analgesic and antipyretic. Beyond pharmaceuticals, it is a crucial component in the production of various dyes, including azo dyes, sulfur dyes, and acid dyes, as well as serving as a photographic developer and an antioxidant. When you are looking to buy 4-Aminophenol, it's essential to consider these diverse applications, as they dictate the required purity and specifications. For instance, pharmaceutical-grade 4-Aminophenol must adhere to stringent standards like USP, BP, EP, and FCC, demanding an assay of ≥98.0% and meticulous quality control, often backed by GMP and SGS certifications.

Why China is a Key Sourcing Hub for 4-Aminophenol

China has emerged as a global leader in chemical manufacturing, offering a vast landscape of suppliers for intermediates like 4-Aminophenol. The advantage of sourcing from China lies in the competitive pricing, driven by economies of scale and efficient production processes. Many Chinese manufacturers have invested heavily in advanced technology and quality management systems, allowing them to produce high-purity chemicals that meet international standards. When searching for a 4-Aminophenol supplier in China, it is advisable to look for those with established export experience, certifications, and a transparent pricing structure. Understanding the minimum order quantities (MOQ) and lead times associated with bulk purchases is also crucial for effective inventory management.

Navigating the Purchase Process: Price, Purity, and Partnership

The price of 4-Aminophenol can fluctuate based on purity, order volume, and market conditions. For procurement managers, obtaining a quote from multiple manufacturers is a standard practice to ensure competitive pricing. However, price should not be the sole determining factor. Purity is critical, especially for pharmaceutical applications where even minor impurities can have significant consequences. Requesting Certificates of Analysis (CoA) for each batch is non-negotiable. Building a strong relationship with a reputable manufacturer or supplier fosters trust and ensures a stable supply chain. Look for partners who offer dedicated customer service and technical support, helping you navigate any challenges and optimize your procurement strategy.

Finding Your Ideal 4-Aminophenol Manufacturer

When selecting a manufacturer for your 4-Aminophenol needs, consider their production capacity, adherence to safety and environmental regulations, and their ability to provide consistent quality. A supplier that offers online purchase support and has a clear inquiry process can streamline your procurement. For example, a dedicated manufacturer will clearly list their product specifications, available packaging (e.g., 25kg bags), and provide easy access to contact details for price inquiries and sample requests. By diligently researching and vetting potential suppliers, you can secure a dependable source of 4-Aminophenol, ensuring the success of your product development and manufacturing operations.
