DL-TROPIC ACID Usage And Synthesis

Chemical Properties

white crystalline solid

Uses

Tropic Acid (Ipratropium EP Impurity C) is a benzoic acid derivative and thus carries anti-fungal properties.

Definition

ChEBI: A 3-hydroxy monocarboxylic acid that is propionic acid in which one of the hydrogens at position 2 is substituted by a phenyl group, and one of the methyl hydrogens is substituted by a hydroxy group.
