Chemical Properties
CLEAR COLOURLESS TO YELLOW LIQUID
Uses
3-Cyclopentylpropionic acid can be used as an organic building blocks in the synthesis of variety of pharmaceutical compound. It is used for the synthesis of Testosterone Cypionate (T155100).
Definition
ChEBI: A monocarboxylic acid that is propionic acid in which one of the methyl hydrogens is substituted by a cyclopentyl group.
Synthesis
Process for the preparation of 3-cyclopentyI-propionic acid, characterized in that cyclopentanone or cyclopentanol in succession in two different temperature ranges with molten alkali hydroxide converts, the temperature of the first area 200 to 270 ° C and the temperature of the second area 290 to 350 ° C, and then the alkali obtained as the 3-cyclopentyl-propionic acid in the free Acid transferred.
