For chemists and procurement managers in the pharmaceutical and fine chemical industries, sourcing high-quality intermediates is paramount. Among these crucial building blocks is 3-Nitrophthalic Acid (CAS 603-11-2), a versatile compound that plays a significant role in various synthetic pathways. Understanding where and how to purchase this material can significantly impact project success, from research and development through to large-scale manufacturing.

When looking to buy 3-Nitrophthalic Acid, several factors deserve careful consideration. Firstly, purity is non-negotiable. As an intermediate, its quality directly influences the yield and purity of the final product. Manufacturers in China, such as those specializing in fine chemical intermediates, often offer high-grade materials. Look for specifications detailing the appearance (typically an off-white to light yellow powder), melting point (around 210°C with decomposition), and solubility characteristics.

Understanding the chemical properties, such as its molecular formula C8H5NO6 and molecular weight of 211.13, is essential for chemists to accurately incorporate it into reaction schemes. Water solubility, stated as 20 g/L at 25°C, is another important parameter for formulation and reaction optimization.

The price of 3-Nitrophthalic Acid can vary based on supplier, quantity, and purity. For bulk purchases, engaging directly with manufacturers or their authorized distributors can offer significant cost advantages. When seeking a reliable 3-Nitrophthalic Acid supplier, it is advisable to inquire about their production capacity, quality control measures, and supply chain reliability. A strong manufacturing base, especially from countries like China known for chemical production, can ensure consistent availability and competitive pricing.

Choosing the right supplier is as critical as the product itself. A reputable manufacturer will provide comprehensive documentation, including Certificates of Analysis (CoA), and adhere to international quality standards. For those in need of this vital intermediate, securing a dependable source for 3-Nitrophthalic Acid is a strategic step towards efficient and successful chemical synthesis.

Ultimately, whether for pharmaceutical research or industrial chemical applications, sourcing 3-Nitrophthalic Acid requires a keen eye for quality, a clear understanding of the chemical’s specifications, and a strategic approach to finding competitive pricing from trusted manufacturers. We are committed to being that trusted supplier.
