IUPAC Name: Ethyl 2-hydroxybenzoate
Structure:
<span style="color:lightgreen;">COOCH₂CH₃</span> group attached to a benzene ring with an <span style="color:lightblue;">ortho-OH</span> group.
Appearance: Colorless to pale yellow liquid.
Odor: Sweet, wintergreen-like (similar to methyl salicylate but milder).
Solubility:
Insoluble in water.
Miscible with alcohols, oils, and organic solvents.
Found in wintergreen leaves, cloves, and some fruits.
Industrially synthesized via esterification of salicylic acid and ethanol (acid-catalyzed).
Fragrance Industry:
Base note in perfumes, soaps, and cosmetics for its sweet, balsamic scent.
Topical Analgesics:
Penetrates skin to relieve muscle/joint pain (converted to salicylic acid locally).
Flavoring Agent:
