For any chemical compound to be effectively utilized in industrial and research applications, a thorough understanding of its properties is essential. 2,3-Pyridinedicarboxylic anhydride (CAS 699-98-9) is no exception. This key intermediate, supplied by NINGBO INNO PHARMCHEM CO.,LTD., possesses specific characteristics that dictate its handling, storage, and optimal use in various synthetic processes.

Primarily, 2,3-pyridinedicarboxylic anhydride is characterized by its appearance as an off-white or light brown crystalline powder. This physical attribute is often the first indicator of its quality. Crucially, the compound boasts a high purity level, typically ≥99%, with a low water content, usually not exceeding 0.3%. These specifications are vital for chemists who rely on predictable reactivity and minimal interference from impurities when they buy 2,3-pyridinedicarboxylic anhydride.

One significant characteristic of 2,3-pyridinedicarboxylic anhydride is its moisture sensitivity. Like many anhydrides, it can react with water, undergoing hydrolysis to form the corresponding dicarboxylic acid. This means that proper storage is critical to maintain its integrity and reactivity. NINGBO INNO PHARMCHEM CO.,LTD. advises storing the material in a clean, dry, and cool place, protected from sunlight and rain, and ideally under a dry inert atmosphere to prevent exposure to atmospheric moisture.

The typical melting point range for 2,3-pyridinedicarboxylic anhydride is between 134°C and 138°C, as reported in various chemical databases. This thermal property is important for process design, particularly in reactions that involve heating. When considering the price of 2,3-pyridinedicarboxylic anhydride, these physical and chemical properties are factored into its overall value proposition.

Furthermore, understanding its compatibility with other substances is important. Incompatible materials often include strong oxidizing agents and moisture, as previously mentioned. Adhering to these handling guidelines is crucial for safety and for preserving the chemical's efficacy. NINGBO INNO PHARMCHEM CO.,LTD. provides safety data sheets (SDS) that offer comprehensive information on the safe handling, storage, and disposal of 2,3-pyridinedicarboxylic anhydride.

In summary, knowledge of 2,3-pyridinedicarboxylic anhydride's properties, including its appearance, purity, moisture sensitivity, and melting point, is fundamental for its successful application. NINGBO INNO PHARMCHEM CO.,LTD. ensures that customers receive detailed information and high-quality product to facilitate their chemical endeavors.
