Description

Xanthurenic Acid is a significant metabolite in the tryptophan-kynurenine pathway, serving as a crucial biomarker and research compound. Its primary value lies in its role as an endogenous modulator of ionotropic glutamate receptors and its association with various metabolic and neurological processes. This makes it essential for researchers and manufacturers in the pharmaceutical, diagnostic, and life science sectors who require high-purity biochemicals for advanced studies and product development.

Application

• Biochemical Research: Used as a key metabolite in studies of the kynurenine pathway, neurochemistry, and metabolic disorders.
• Pharmaceutical Development: Serves as a reference standard and intermediate in the research of novel therapeutic agents targeting neurological and inflammatory conditions.
• Diagnostic Reagents: Employed in the formulation of calibration standards and assay kits for quantifying tryptophan metabolites in clinical and research laboratories.
• Metabolomics & Biomarker Studies: A critical analytical standard for LC-MS, HPLC, and other analytical techniques to investigate disease biomarkers.
• Enzymology Studies: Utilized as a substrate or inhibitor in enzymatic assays related to aminotransferase and dehydrogenase activity.
