Product Introduction：
Soluble in alcohol and ether, practically insoluble in petroleum ether.
Product Usage：
Tropic acid can be used as a substrate in:
• Esterification of carboxylic acids and alcohols in the presence of dried Dowex H+/NaI catalyst system.
• Multistep synthesis of cyclic pentadepsipeptides.
• Synthesis of an isocoumarin derivative by reacting with tetracyanobenzene (TCNB) via multicomponent photo reaction.
Tropic acid is used in the synthesis of (−)-anisodine, atropine and hyoscyamine.
