Salicylic acid has long been a key starting material for making acetylsalicylic acid (ASA or aspirin). [8] ASA is prepared by the acetylation of salicylic acid with the acetyl group from acetic anhydride or acetyl chloride. [17] ASA is the standard to which all the other non-steroidal anti-inflammatory drugs are compared. In veterinary medicine ...
In organic chemistry, a carboxylic acid is an organic acid that contains a carboxyl group (−C(=O)−OH) [1] attached to an R-group. The general formula of a carboxylic acid is often written as R−COOH or R−CO 2 H, sometimes as R−C(O)OH with R referring to an organyl group (e.g., alkyl, alkenyl, aryl), or hydrogen, or other groups ...
The systematic IUPAC name is not always the preferred IUPAC name, for example, lactic acid is a common, and also the preferred, name for what systematic rules call 2-hydroxypropanoic acid. This list is ordered by the number of carbon atoms in a carboxylic acid.
Salicylic acid is acetylated to form aspirin. In chemistry, acetylation is an organic esterification reaction with acetic acid. It introduces an acetyl group into a chemical compound. Such compounds are termed acetate esters or simply acetates. Deacetylation is the opposite reaction, the removal of an acetyl group from a chemical compound.
"Salicylic acid is a topical medication used to treat acne and a variety of other skin conditions, like warts and psoriasis," says double-board-certified dermatologist, Maya Thosani, MD. While it ...
The term "acetyl" was coined by the German chemist Justus von Liebig in 1839 CE to describe what he incorrectly believed to be the radical of acetic acid (the main component of vinegar, aside from water), which is now known as the vinyl group (coined in 1851 CE); "acetyl" is derived from the Latin acētum, meaning "vinegar."
Salicylic acid is treated with acetic anhydride, an acid derivative, causing a chemical reaction that turns salicylic acid's hydroxyl group into an ester group (R-OH → R-OCOCH 3). This process yields aspirin and acetic acid , which is considered a byproduct of this reaction.
The reactivity of a functional group can be modified by other functional groups nearby. Functional group interconversion can be used in retrosynthetic analysis to plan organic synthesis. A functional group is a group of atoms in a molecule with distinctive chemical properties, regardless of the other atoms in the molecule. The atoms in a ...
