When you're looking to buy this essential chemical, understanding where and how to source it effectively can make a significant difference in your project's success. As a prominent manufacturer and supplier based in China, we offer insights into what buyers should prioritize.

Understanding Pyridine-3,5-dicarboxylic Acid

Pyridine-3,5-dicarboxylic acid, also known as dinicotinic acid, is a heterocyclic organic compound characterized by its pyridine ring substituted with two carboxylic acid groups at the 3 and 5 positions. Its chemical formula is C7H5NO4, with a molecular weight of 167.12 g/mol. Typically appearing as a white crystalline powder, it boasts a high melting point, often exceeding 300°C, indicating its thermal stability.

Key Applications in Research and Development

The primary utility of pyridine-3,5-dicarboxylic acid lies in its function as a pharmaceutical intermediate. It serves as a crucial building block for synthesizing a wide array of active pharmaceutical ingredients (APIs). Its structure allows for diverse chemical modifications, making it valuable in the exploration of new therapeutic agents. Beyond pharmaceuticals, it finds application in material science and as a versatile reagent in complex organic synthesis pathways. For researchers in drug discovery, obtaining a reliable supply of this compound is critical for consistent experimental outcomes.

What Buyers Should Look For in a Supplier

When you intend to purchase pyridine-3,5-dicarboxylic acid, several factors are crucial for ensuring you receive a product that meets your stringent requirements. Firstly, purity is non-negotiable, especially for pharmaceutical applications. High-purity grades, often 98% or 99% minimum, are essential to avoid unwanted side reactions or impurities in your final product. Look for suppliers who clearly state their purity levels, often verified by analytical techniques like HPLC.

Secondly, supplier reliability is key. As a buyer, you need assurance of consistent availability and timely delivery. Partnering with an established manufacturer in China, one with a track record of quality and service, can mitigate supply chain risks. Understanding their production capacity and quality control processes provides confidence in their ability to meet your ongoing needs. For procurement managers, securing a dependable source for essential intermediates like CAS 499-81-0 is a strategic advantage.

Thirdly, technical specifications and documentation are important. Always request a Certificate of Analysis (CoA) that details the lot-specific purity, physical properties, and analytical methods used. Knowledgeable suppliers will readily provide this information, along with Safety Data Sheets (SDS).

Finding the Right Manufacturer in China

China has emerged as a global hub for chemical manufacturing, offering competitive pricing and a vast production capacity.
