History of aspirin Hermann Hildebrandt). In 1894, the young chemist Felix Hoffmann joined the pharmaceutical group. Dreser, Eichengrün and Hoffmann would be the key figures in the development of acetylsalicylic acid as the drug Aspirin (though their respective roles have been the subject of some contention). In 1897, Hoffmann started working to find a less irritating substitute for salicylic acid. It is generally accepted that he turned to this idea because his father was suffering the side effects of taking sodium salicylate for rheumatism. In 1853, Charles Frédéric Gerhardt had published the first methods to prepare acetylsalicylic acid. In the course of his
Armstrong's acid acids, which are precursors to amino derivatives. The disodium salt is sometimes used as a divalent counterion for forming salts of basic drug compounds, as an alternative to the related mesylate or tosylate salts. When used in this way such a salt is called a naphthalenedisulfonate salt, as seen with the most common salt form of the stimulant drug CFT. The disodium salt is also used as an electrolyte in certain kinds of chromatography. Armstrong's acid Armstrong's acid (naphthalene-1,5-disulfonic acid) is a fluorescent organic compound with the formula CH(SOH). It is one of several isomers of naphthalenedisulfonic acid. It a
