Quinolinic acid, also known as 2,3-Pyridinedicarboxylic acid and identified by CAS number 89-00-9, is a vital organic compound that serves as a key intermediate in the pharmaceutical industry. Its significance lies in its ability to act as a precursor for synthesizing a range of important therapeutic agents, most notably antibiotics.

One of the most prominent applications of quinolinic acid in this field is its use in the synthesis of Moxifloxacin hydrochloride. Moxifloxacin is a broad-spectrum fluoroquinolone antibiotic used to treat a variety of bacterial infections. The reliable supply of high-purity quinolinic acid is essential for pharmaceutical manufacturers to ensure the efficacy and safety of the final drug product. Companies that buy quinolinic acid for these purposes rely on manufacturers like NINGBO INNO PHARMCHEM CO.,LTD. for consistent quality.

Beyond antibiotics, quinolinic acid's chemical properties make it valuable in the development of other pharmaceutical compounds. Its involvement in the kynurenine pathway, a metabolic process involving the amino acid tryptophan, also highlights its biological relevance. While this aspect is more related to neuroscience and the compound's neuroactive properties, it underscores the multifaceted nature of quinolinic acid.

The production of pharmaceutical-grade quinolinic acid requires stringent quality control and adherence to regulatory standards. Manufacturers must ensure high purity and minimal impurities to meet the demanding requirements of drug synthesis. This focus on quality is a hallmark of responsible chemical suppliers, ensuring that essential pharmaceutical intermediates are available for the development of life-saving medications.
