Description

5-Pyridoxic Acid is a key metabolite of vitamin B6 (pyridoxine), serving as a primary biomarker for assessing nutritional status and metabolic function. This compound is essential for research and development in clinical diagnostics and nutritional science. It is primarily utilized by manufacturers of in-vitro diagnostic (IVD) reagents, clinical research organizations, and pharmaceutical companies developing analytical standards.

Application

• Clinical Diagnostic Reagents: A critical calibrator and reference standard in HPLC and LC-MS/MS kits for the quantitative determination of vitamin B6 status in human serum and plasma.
• Biochemical Research: Used as a high-purity reference compound in studies investigating pyridoxine metabolism, enzyme cofactor functions, and related metabolic pathways.
• Pharmaceutical Analysis: Serves as an analytical standard for quality control and method development in the assay of vitamin B6 and its metabolites in pharmaceutical formulations.
• Nutritional Science: Employed in research to evaluate dietary intake, bioavailability, and the biochemical efficacy of vitamin B6 supplements and fortified foods.
• Metabolomics: A significant metabolite identified in metabolomic profiling for discovering biomarkers related to cardiovascular, neurological, and inflammatory diseases.
