Description

4-Pyridoxic Acid Lactone is a key metabolite and chemical intermediate derived from vitamin B6 metabolism. This compound matters for its role as a reference standard in clinical diagnostics and as a crucial building block in pharmaceutical research and synthesis. It is primarily needed by manufacturers and research institutions in the pharmaceutical, diagnostic, and fine chemical industries for developing analytical methods and active pharmaceutical ingredients.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the quantification of vitamin B6 metabolites in biological samples via HPLC or LC-MS/MS.
• Diagnostic Reagent Intermediate: Serves as a key precursor in the development of diagnostic kits and assays for assessing nutritional status and metabolic disorders.
• Biochemical Research: Employed in metabolic pathway studies, enzyme activity assays, and research related to pyridoxine (Vitamin B6) metabolism.
• Fine Chemical Synthesis: Acts as a specialized building block for the synthesis of more complex molecules in medicinal chemistry and drug discovery.
• Nutraceutical Analysis: Utilized in quality control laboratories to analyze and validate the content of vitamin B6 and its derivatives in fortified foods and dietary supplements.

Quality Control

Our 4-Pyridoxic Acid Lactone is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets high-purity standards suitable for research and pharmaceutical applications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation.
