Pyridoxal 5′-phosphate (PLP), also known as vitamin B6 phosphate or P5P, is the biologically active coenzyme form of vitamin B6. This certified reference material (CRM) solution is provided for use in quantitative analytical methods requiring accurate calibration and validation of PLP measurements.

This single-component solution is suitable for preparation of calibration standards, linearity solutions, quality control samples, and method validation protocols in clinical, pharmaceutical, and nutritional testing laboratories. It is commonly applied in assays measuring vitamin B6 status, enzymatic activity, fortified foods, dietary supplements, and biological samples using chromatographic techniques such as LC or GC.

Supplied with traceable documentation, this CRM supports analytical accuracy, reproducibility, and regulatory compliance across research, clinical diagnostics, and quality assurance environments.

This certified reference material is supplied with a certificate of analysis providing traceable concentration values suitable for calibration, method validation, and analytical quality control.

Shipping and Storage Notice
Please note that shipping and long-term storage conditions for certified reference materials may differ. Manufacturers determine the most appropriate shipping method based on product stability and shipping data. Some CRM standards may ship at ambient temperature even though recommended long-term storage conditions are refrigerated or frozen. This does not affect product integrity when handled according to manufacturer documentation.
