For procurement managers and R&D scientists in the pharmaceutical and fine chemical sectors, securing a consistent supply of high-purity chemical intermediates is paramount. Among these vital compounds is 4-Aminophthalic Acid (CAS 5434-21-9), a versatile building block with diverse applications. When seeking to buy this essential material, understanding the landscape of Chinese manufacturers can unlock significant advantages in terms of both quality and cost.

Understanding 4-Aminophthalic Acid and Its Importance

4-Aminophthalic Acid, with the molecular formula C8H7NO4, is primarily valued for its role as an intermediate in the synthesis of medicines and dyes. Its purity level is critical for downstream applications, ensuring reliable reaction outcomes and the integrity of the final products. Whether you are involved in the synthesis of folic acid, azo dyes, or complex pharmaceutical APIs, the quality of your 4-Aminophthalic Acid supplier directly impacts your success. Many researchers also utilize it for calibration purposes and as a reagent in specific chemical determinations.

Navigating the Chinese Chemical Market for Procurement

China has emerged as a global hub for chemical manufacturing, offering a vast array of suppliers for specialized compounds like 4-Aminophthalic Acid. For purchasing professionals, identifying reputable manufacturers is key. Look for suppliers who can provide clear specifications, including assay percentages (e.g., ≥99%min), physical properties like appearance (yellow to white powder), and melting point (typically around 334°C). A trusted manufacturer will also offer comprehensive documentation such as Certificates of Analysis (CoA) and Safety Data Sheets (SDS).

When you are ready to inquire about pricing or place an order, leveraging keywords like '4-aminophthalic acid manufacturer China,' 'buy 4-aminophthalic acid,' or 'CAS 5434-21-9 price' will help you connect with suitable suppliers. Many Chinese chemical companies are eager to provide quotes and samples, facilitating your sourcing process. They often cater to both small-scale R&D needs and large-volume industrial production, offering flexible packaging and delivery options.

Key Considerations for Buyers

When evaluating potential suppliers, consider their production capacity, quality control measures, and customer service. A supplier who offers transparent communication and robust technical support can be an invaluable partner. For bulk purchases, negotiating directly with a manufacturer can yield significant price advantages. Ensure they can meet your specific delivery timelines and any regulatory requirements.

In conclusion, sourcing 4-Aminophthalic Acid from China offers a strategic advantage for businesses worldwide. By conducting thorough research and focusing on qualified manufacturers, you can secure a high-quality, cost-effective supply of this essential chemical intermediate, empowering your innovation and production goals. If you are looking to purchase this compound, reaching out to a dedicated supplier for a quote is the first step towards a successful partnership.
