Abstract

The ^1^H and ^13^C NMR spectra of pyridoxine (vitamin B~6~) and its dibutylstannylene derivative were assigned from proton detected ^1^H^13^C heteronuclear multiple bond correlation (^1^H^13^C HMBC) spectra.

## Abstract During the terminal heat sterilization of the lipid emulsion final dose formulation of the photodynamic therapeutic (PDT) agent tin ethyl etiopurpurin (SnET2), a new degradant was observed at very low levels. The degradant, which was prone to photo‐instability, was isolated by preparati
