Description

3-Bromocyclopentane-1-Carboxylic Acid CAS NO 885953-19-5 is a versatile brominated cyclopentane derivative that serves as a key chiral building block in advanced organic synthesis. Its unique structure, featuring both a carboxylic acid and a bromine substituent on a cyclopentane ring, makes it invaluable for constructing complex molecular architectures. This intermediate is primarily sought after by research and development teams in the pharmaceutical and agrochemical industries for applications in medicinal chemistry and the synthesis of novel active ingredients.

Application

• Pharmaceutical Intermediate: A crucial chiral synthon for the development of novel active pharmaceutical ingredients (APIs), particularly in central nervous system (CNS) and metabolic disorder research.
• Agrochemical Synthesis: Used in the research and production of advanced herbicides, fungicides, and plant growth regulators that require specific stereochemistry.
• Ligand and Catalyst Development: Serves as a precursor for synthesising chiral ligands and organocatalysts used in asymmetric synthesis.
• Material Science Research: Employed in the creation of specialty polymers and liquid crystals where the bromocyclopentane core imparts specific physical properties.
• Chemical Biology Probes: Useful for synthesising tagged molecules and probes for studying biological pathways and protein interactions.
• Custom Synthesis and Contract Manufacturing: A high-value starting material for custom synthesis projects and scale-up processes in fine chemical production.
