Hoffman s acetylsalicylic acid competed with the other salicylate compounds after its initial synthesis. In 1899 Hoffman s employer, the Bayer Company, founded in 1861 by Friedrich Bayer (1825-1880), began to market acetylsalicylic acid under the name Aspirin. The term aspirin was derived by combining the letter a from acetyl and spirin from spiric acid. Spiric acid is another name for salicylic acid found in plants of the genus Spirea. Bayer pro-... 

Hoffmans next task was to convince his employer, Bayer, founded in 1861 by Friedrich Baeyer (1825-1880), to market the product. In 1899, Bayer began to market acetylsalicylic... 

That s quite a claim for the little pill that was concocted in 1897 by Felix Hoffmann, a chemist working for the Bayer company in Germany. While Hoffmann did synthesize the first commercial sample of acetylsalicylic acid, as aspirin is known generically, he wasn t the first to produce the substance in the laboratory. That honor goes to Karl Friedrich Gerhardt, who, in 1853 at Montpellier University in France, concocted an impure version with an eye towards improving on the effects of salicylic acid, a commonly used painkiller. At the time salicylic acid was extracted from the leaves of the meadowsweet plant and used for the treatment of fevers and pain, particularly of the arthritic variety. But it had to be taken in...

But unfortunately salicylic acid attacks the mucous membranes of the mouth and esophagus and causes gastric pain that may be worse than the discomfort it was meant to cure. Felix Hoffmann, a chemist for Friedrich Bayer, a German dye company, reasoned that the corrosive nature of salicylic acid could be altered by addition of an acetyl group and in 1893 the Bayer Company obtained a patent on acetylsalicylic acid, despite the fact that it had been synthesized some forty years previously by Charles Gerhardt. Bayer coined the name Aspirin for their new product to reflect its acetyl nature and its natural occurrence in the Spiraea plant. Over the years they have allowed the term aspirin to fall into the public domain so it is no longer capitalized. The manufacturers of Coke and Sanka work hard to prevent a similar fate befalling their products.

Protection of OH groups. The Bohn-Schmidt reaction, discovered independently in rival German dye firms (Badische Company, Friedrich Bayer), consists in hydroxylation of an anthraquinone with fuming sulfuric acid and boric acid, often in the presence of a catalytic amount of mercury.

In 1863 Friedrich Bayer cofounded a dye manufacturing company in Germany. Eight years after his death, in 1888 the company opened a pharmaceutical division. A decade later, employee Felix Floffman, concerned over his father s aches and pains, discovered a useful chemical in the waste of the dye process. Known as aspirin, it remains a popular painkiller over 100 years later.
