Aniline Germany. Today, the name of BASF, originally "Badische Anilin- und Soda-Fabrik" (English: Baden Aniline and Soda Factory), now the largest chemical supplier, echoes the legacy of the synthetic dye industry, built via aniline dyes and extended via the related azo dyes. The first azo dye was aniline yellow. In the late 19th century, aniline emerged as an analgesic drug, its cardiac-suppressive side effects countered with caffeine. During the first decade of the 20th century, while trying to modify synthetic dyes to treat African sleeping sickness, Paul Ehrlich – who had coined the term "chemotherapy" for his "magic bullet" approach to
Aniline acetate test pentoses (sugars containing five carbon atoms) to produce furfural. The reaction of furfural and aniline produces a bright pink color. Hexoses, which are sugars which contain six carbons, are not dehydrated to furfural, and so they do not produce a pink color. 3-Furanaldehyde responds to the usual tests for aldehydes, but unlike 2-furanaldehyde it gives no color test with aniline acetate. Aniline acetate test The aniline acetate test is a chemical test for the presence of certain carbohydrates, in which they are converted to furfural with hydrochloric acid, which reacts with aniline acetate to produce a bright pink color.
