'acetylsalol' originates from the combination of 'acetyl' and 'salol', where 'acetyl' refers to the acetyl group derived from acetic acid, and 'salol' is a compound derived from salicylic acid.

'acetylsalol' was synthesized by combining acetyl chloride with salol, resulting in a compound used in pharmaceuticals.

Initially, it was used primarily for its analgesic properties, but over time, its use expanded to include antipyretic applications.
