How was saccharin first made?
Saccharin was produced first in 1879, by Constantin Fahlberg, a chemist working on coal tar derivatives in Ira Remsen's laboratory at the Johns Hopkins University. Fahlberg noticed a sweet taste on his hand one evening, and connected this with the compound benzoic sulfimide on which he had been working that day.
How sweet is saccharin?
The substance is about 300 times as sweet as sugar, and it doesn't have any calories. What’s not to love about that? But not everything in saccharin's history is sweet. The story of the sugar substitute begins in the labs of Johns Hopkins University, where Dr. Ira Remsen became the first chemistry professor in 1876.
What is saccharin used for in food?
Saccharin. Sodium saccharin (benzoic sulfimide) is an artificial sweetener with effectively no food energy. It is about 300–400 times as sweet as sucrose but has a bitter or metallic aftertaste, especially at high concentrations. Saccharin is used to sweeten products such as drinks, candies, cookies, and medicines.
How is saccharin produced from toluene?
Saccharin can be produced in various ways. The original route by Remsen and Fahlberg starts with toluene; another route begins with o-chlorotoluene. Sulfonation of toluene by chlorosulfonic acid gives the ortho and para substituted sulfonyl chlorides.

Saccharin had its fans, however—including one in the White House.
