Pyridoxine 3,4-dioctanoate (PIN-3,4DO) was readily changed into pyridoxine 4,5-dioctanoate (PIN-4,5DO) under alkaline treatment with 0.1 N KOH at room temperature. This rearrangement also occured with pyridoxine 3,4-dilaurate and pyridoxine 3,4-dipalmitate at the same condition. Solubility in organic solvents and molar extinction of PIN-4,5DO and PIN-3,4DO were studied.
