For professionals in the pharmaceutical industry, identifying reliable and high-quality chemical intermediates is paramount. Among these, Pyridine-2,5-dicarboxylic Acid (CAS: 100-26-5) stands out as a crucial building block for a variety of applications, most notably in the development of antiviral agents. Understanding its properties and sourcing it effectively can significantly impact research and development timelines and product efficacy.

Pyridine-2,5-dicarboxylic Acid, also known by synonyms like Isocinchomeronic acid, is a heterocyclic organic compound characterized by its two carboxyl groups attached to a pyridine ring. This structural arrangement makes it highly versatile for chemical transformations. Its chemical formula is C7H5NO4, and it has a molecular weight of 167.12 g/mol. Typically appearing as a yellow to green fine crystalline powder, it exhibits stability under normal conditions, a vital characteristic for any intermediate intended for complex synthesis pathways.

The primary driver for the demand of Pyridine-2,5-dicarboxylic Acid in the pharmaceutical sector stems from its use in the preparation of new derivatives. Specifically, researchers have utilized it to synthesize compounds with potent antiviral activities, making it a key ingredient in the discovery of next-generation therapeutics. Beyond its antiviral applications, its utility extends to the synthesis of other fine chemicals, including intermediates for niacin, pesticides, and dyes, showcasing its broad industrial relevance.

For procurement managers and R&D scientists, sourcing this intermediate requires careful consideration of purity, consistency, and supplier reliability. A reputable manufacturer in China can offer a competitive advantage, providing high-purity material (often exceeding 95% or 98%) at attractive price points. Establishing a relationship with a trusted supplier ensures not only cost-effectiveness but also the stability of the supply chain, which is critical for ongoing projects and scaled-up production. When looking to buy Pyridine-2,5-dicarboxylic Acid, prioritizing manufacturers with robust quality control processes and transparent documentation, such as Certificates of Analysis (COA), is essential.

Engaging with suppliers for bulk purchases or requesting samples for initial evaluation are standard practices. The global market offers various grades and packaging options, from small research quantities (e.g., 5g, 25g) to industrial scales (e.g., 1kg, 25kg). For those planning long-term projects, securing a consistent supply of Pyridine-2,5-dicarboxylic Acid from a reliable manufacturer in China is a strategic move that supports both innovation and commercial viability in the pharmaceutical and chemical industries.
