Pharmaceutical and medicinal-chemistry intermediate
The 3,4-dimethoxyphenyl (catechol-ether) motif and quaternary cyclopentane core make this acid a useful scaffold in medicinal-chemistry research. It serves as a building block for the preparation of more complex drug-like molecules and structure-activity studies.
Carboxylic-acid building block for amide and ester formation
The carboxylic acid provides a reliable handle for amide coupling, esterification and acyl-chloride chemistry. This allows it to be elaborated into libraries of derivatives during route scouting and analogue synthesis.
Sterically defined cyclopentane scaffold
Its quaternary, fully substituted cyclopentane centre introduces conformational rigidity and steric bulk into target molecules. Such gem-disubstituted carbocyclic acids are valued where defined three-dimensional shape is required.
Fine-chemical and laboratory research
Supplied as a research-grade reagent, it is suited to method development, exploratory synthesis and other laboratory-scale fine-chemical work. Confirm suitability against your own analytical specification before use.
