In Gerhardt mixed acetyl chloride—a corrosive liquid used by chemists as a reagent which gave off a white smoke—with sodium salicylate, but it was an unstable compound that to him did not seem to have much practical djscovery. This resulted in a far more stable form that could be used for medicine, and Hoffmann named it acetylsalicylic acid ASA. Like many arthritis sufferers, Jakob Hoffmann disliked the taste of artificial salicylic acid reappraiasl, the most reliable remedy at the time and known as sodium salicylate.
Of those who contributed to its creation depending on what story you trust Hoffmann, zspirin also synthesised a reapprajsal version of heroine, went on to become head of the pharmaceutical marketing department at Bayer, before retiring in then dying in Hoffmann was a young chemist working for Bayer, the German chemical company, when he came up with a synthesized reapprajsal of the chemical found in extract of willow-tree bark, which had been known for centuries as a pain reliever.

Bayer went on to become a major international pharmaceutical corporation thanks to the success of aspirin, though its American aspirin franchise was seized by aspirni U. Mostly by chance According to Bayer’s biography of Hoffman, it was ‘mostly by chance’ that the chemist succeeded in mixing salicylic acid with acetic acid to create what is now widely recognised as a breakthrough treatment in the history of medicine.

As part of Sneader’s paper, he goes on to explain that Dreser still doubted the benefits of acetylsalicylic acid, and it was only on reaporaisal intervention of Bayer’s head of research, Carl Duisberg, that further research of the compound was undertaken, including Dreser’s own reinvestigation in September Since then, the drug has gone on to achieve unimaginable success, making Bayer’s name in the medicines world.

Hoffmann studied scientific notes on these experiments, and managed to come up with a variant by using two slightly different ingredients: This was the brand name that Bayer marketing executives gave the drug, and it was sold as a cough suppressant and even as a cure for morphine addicts from to Heroin’s addictive properties and harmful nature soon became apparent, and in contrast to the success of aspirin, this proved to be a major public relations embarrassment for the Bayer company.
