Description

Cyclopentanol, 2-Bromo- (7Ci,9Ci) CAS NO 74305-04-7 is a halogenated cyclopentanol derivative, a versatile chiral building block in advanced organic synthesis. This compound matters for its ability to introduce both bromine and hydroxyl functional groups into molecular frameworks, enabling the construction of complex, stereodefined structures. It is needed by research chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for applications such as medicinal chemistry, ligand synthesis, and the development of novel materials.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of active pharmaceutical ingredients (APIs) and drug candidates, particularly those requiring cyclopentane-based scaffolds.
• Agrochemical Synthesis: Used in the research and development of novel pesticides, herbicides, and plant growth regulators where the bromocyclopentanol moiety imparts specific biological activity.
• Ligand and Catalyst Preparation: Serves as a precursor for chiral ligands used in asymmetric catalysis, such as phosphines and aminols, critical for enantioselective manufacturing processes.
• Material Science Research: Employed in the development of specialty polymers, liquid crystals, and other advanced materials that benefit from its rigid, functionalized cyclic structure.
• Organic Synthesis Building Block: Utilized in multi-step synthetic routes for cyclopentane annulation, nucleophilic substitution reactions, and as a protected diol equivalent.
• Academic and R&D Laboratories: A valuable reagent for methodological studies in synthetic organic chemistry and for exploring new chemical transformations.
