Description

4-Pyridoxic Acid 5'-Phosphate is a key phosphorylated metabolite of vitamin B6 (pyridoxine). This compound matters significantly as a crucial biochemical intermediate and analytical standard for research into vitamin B6 metabolism and nutritional status. It is primarily needed by pharmaceutical R&D laboratories, diagnostic kit manufacturers, and academic institutions conducting metabolic studies.

Application

• Biochemical Research: Used as a high-purity reference standard in studies of vitamin B6 metabolism and enzymatic pathways.
• Diagnostic Reagents: Serves as a critical calibrant and component in clinical diagnostic kits for measuring vitamin B6 levels in biological samples.
• Pharmaceutical Development: Employed as an intermediate or analytical standard in the development and quality control of nutraceuticals and vitamin supplements.
• Metabolomics: Acts as a defined metabolite for mass spectrometry and chromatography-based metabolomic profiling.
• Enzyme Substrate: Utilized in enzymatic assays to study the activity of phosphatases and other enzymes involved in vitamin B6 cycle.
