Acetanilide Usage And Synthesis

Chemical Properties	Acetanilide, also known as Nphenylacetamide, acetanil, or acetanilide is a white to gray solid with molecular formula CH3CONHC6H5. It is an odorless colorless, glossy, crystalline powder or flakes. Acetanilide was the first aniline derivative found to possess analgesic as well as antipyretic properties and was quickly introduced into medical practice (Weast, 1981; Gnanasambandan et al., 2014). Later, it was established that in the human body it is mostly metabolized to paracetamol, this compound being responsible for the analgesic and antipyretic properties of acetanilide (Bertolini et al., 2006; Gnanasambandan et al., 2014). In addition, it was discovered that it has unacceptable toxic effects, so that acetanilide is no longer used as a drug. Acetanilide is mainly used as an intermediates in the synthesis of pharmaceuticals and dyes, as an additive for hydrogen peroxide and cellulose ester varnishes, and as a plasticizer in polymer industry as well as accelerator in the rubber industry.
Physical properties	White glossy flake crystal or white crystalline powder. Slightly soluble in cold water, soluble in hot water, methanol, ethanol, ether, chloroform, acetone, glycerol and benzene.
History	The department of internal medicine at the University of Strassburg in the 1880s was noted for its investigations into intestinal worms. Adolf Kussmaul, the director, asked two young assistants, Arnold Cahn and Paul Hepp, to treat patients with naphthalene as it had been used elsewhere as an internal antiseptic. The young doctors were disappointed with the initial results, but Hepp persevered with the naphthalene treatment in a patient suffering from a variety of complaints besides worms. Surprisingly, the fever chart revealed a pronounced antipyretic effect from this treatment. This had not been observed before, but further investigation revealed that Hepp had wrongly been supplied by Kopp’s Pharmacy in Strassburg with acetanilide instead of naphthalene! Cahn and Hepp lost no time in publishing a report on their discovery of a new antipyretic. For many years after its discovery in 1886, Acetanilide was used as an alternative to aspirin (i.e. acetyl salicylate) - an analgesic (painkiller) and antipyretic (fever reducing) drug to relieve e.g. headache, menstrual pain, and rheumatic pain. Under the name “Acetanilide” it formerly appeared in the formula of a number of patent medicines and over the counter drugs. In 1948, Julius Axelrod and Bernard Brodie discovered that Acetanilide is much more toxic in these applications than other drugs, causing methemoglobinemia and ultimately causing damage to the liver and kidneys. Thus, Acetanilide has largely been replaced by less toxic drugs, in particular acetaminophen (i.e. paracetamol), which is a metabolite of Acetanilide and whose use Axelrod and Brodie suggested in the same study.
Uses	Acetanilide is used as an intermediate in the synthesis of rubber accelerator, dyes and camphor. It is also used in the synthesis of penicillin and other pharmaceutical products. It is involved in the preparation of 4-acetamidobenzenesulfonyl chloride, which is an intermediate during the synthesis of sulfa drugs. Further, it is employed as a experimental photographic developer. In addition to this, it is used to stabilize cellulose ester varnishes.
Application	Acetanilide is used as an inhibitor of hydrogen peroxide decomposition and to stabilize cellulose ester varnishes. It is also used in the intermediation of rubber accelerator synthesis, dyes and dye intermediate synthesis, and camphor synthesis. Acetanilide is used for the production of 4-acetamidobenzenesulfonyl chloride, a key intermediate for the manufacture of the sulfa drugs. It is also a precursor in the synthesis of penicillin and other pharmaceuticals. In the 19th century acetanilide was one of a large number of compounds used as experimental photographic developers. Acetanilide is used as a EOF (electroosmotic flow) marker in the studies of affinity capillary electrophoresis for drug–protein binding. Acetanilide undergoes palladium-catalyzed cross-coupling reaction to form ortho-acylacetanilide.

Reactive Group:

Amides and Imides

Reactivity Profile:

ACETANILIDE is an amide. Flammable gases are formed by the reaction of organic amides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).

Autoignition Temperature:

1004 °F (NTP, 1992)|985 + or - 10 °F.
