Quinolinic acid, scientifically known as 2,3-Pyridinedicarboxylic acid and carrying the CAS number 89-00-9, is a white to off-white crystalline powder with distinct chemical and physical characteristics that are vital for its industrial applications. Understanding these properties is key for ensuring its effective use and safe handling.

Physically, quinolinic acid presents as a solid, typically a powder, and is known for its solubility in water and polar organic solvents like ethanol. This solubility profile makes it amenable to various chemical reactions and formulations. Its melting point is reported to be between 188-190°C, with decomposition occurring at this temperature. The compound's stability is generally good under recommended storage conditions, which are crucial for maintaining its purity and efficacy. Manufacturers, such as NINGBO INNO PHARMCHEM CO.,LTD., advise storing quinolinic acid in cool, dry, and well-closed containers, away from moisture, strong light, and heat sources.

The chemical structure of quinolinic acid, a dicarboxylic acid with a pyridine backbone, dictates its reactivity and applications as an intermediate. It is frequently used in syntheses where precise control over reaction conditions is necessary. For businesses intending to buy quinolinic acid, reviewing the material's safety data sheet (SDS) and adhering to handling recommendations is paramount. These guidelines typically include using appropriate personal protective equipment (PPE) and ensuring adequate ventilation in areas where the compound is handled.

Proper storage and handling are not only about maintaining product quality but also about ensuring workplace safety. By following best practices for chemical management, industries can reliably utilize quinolinic acid in their manufacturing processes, whether for agrochemicals, pharmaceuticals, or research purposes, maximizing its value as a versatile chemical intermediate.
