On This Day In Chemistry

February 3rd

French chemist Edmond Frémy died on this day in 1894

He is best known for Frémy’s salt (potassium nitrosodisulfonate), which is a strong oxidising agent that he discovered in 1845. This salt is a long-lived free radical that can be used as a standard in electron paramagnetic resonance (EPR) spectroscopy.
