About Pyridoxine-d3 Hydrochloride

Pyridoxine-d3 Hydrochloride is a stable isotope labelled analogue related to Pyridoxine carrying the CAS registry number 1189921-12-7. The compound has the formula C8H12ClNO3, corresponding to a molecular weight of 208.66 g/mol. It is also known as Pyridoxine-d3 HCl or Vitamin B6-d3 hydrochloride.

It is supplied as a solid. Keep the vial tightly closed, protected from light and humidity, at the temperature stated on the Certificate of Analysis. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

This isotope-labelled compound is used as an internal standard for LC-MS and LC-MS/MS quantitation of Pyridoxine and related analytes in bioanalytical, pharmacokinetic and impurity studies. It is used across pharmaceutical manufacturing and academic and industrial research.

Standard pack sizes are 10 mg, 25 mg, 50 mg and 100 mg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
