Description

4-Pyridoxic Acid is a key metabolite of vitamin B6 (pyridoxine) and serves as a critical biomarker for assessing vitamin B6 status in biological systems. Its high purity is essential for ensuring accurate analytical results in clinical and nutritional research. This compound is primarily required by manufacturers of diagnostic kits, reference standards, and research institutions focused on metabolism, nutrition, and pharmaceutical development.

Application

• Biochemical Research & Reference Standard: Used as a high-purity analytical standard in HPLC, LC-MS, and other chromatographic methods for quantifying vitamin B6 metabolites in biological samples.
• Diagnostic Kit Manufacturing: A critical raw material in the production of clinical diagnostic kits and immunoassays designed to measure vitamin B6 deficiency or metabolic disorders.
• Nutritional Science & Metabolism Studies: Employed in research to understand vitamin B6 metabolism, bioavailability, and its role in human health and disease.
• Pharmaceutical Intermediate: Serves as a potential intermediate or starting material in the synthesis of more complex molecules for pharmaceutical applications.
• Quality Control Laboratories: Utilized as a certified reference material (CRM) for method validation and quality assurance in food, supplement, and pharmaceutical testing.
