Product Overview

Product Name: 1-Bromo-5-fluoropentane (5-Fluoropentyl Bromide)

CAS No.: 407-97-6

Molecular Formula: C₅H₁₀BrF

Molecular Weight: 169.04

EINECS No.: 255-647-3

1-Bromo-5-fluoropentane (CAS 407-97-6) is an organohalogen compound containing both bromine and fluorine atoms. It appears as a colorless to light yellow clear liquid with a molecular weight of 169.04. The compound is slightly soluble in water but soluble in methanol and other organic solvents.

With a purity of ≥99.0%, this bifunctional building block features two reactive sites—the bromine atom (leaving group for nucleophilic substitution) and the fluorine atom (introducing fluorinated functionality). This dual reactivity makes it a versatile intermediate in organic synthesis and pharmaceutical research

Key Applications:

1. Pharmaceutical Research (Primary Application)

1-Bromo-5-fluoropentane is used as a key intermediate in the preparation of ¹⁸F-labeled (anilido)piperidine derivatives, which serve as μ-opioid receptor imaging agents for positron emission tomography (PET) studies. This application is critical for neuroscience research and medical imaging.

2. Organic Synthesis

Acts as a versatile building block for introducing the 5-fluoropentyl group into target molecules. The bromine atom readily undergoes nucleophilic substitution reactions (e.g., with amines, cyanides, hydroxides) to form various derivatives.

3. Materials Science

Can be used in the synthesis of fluorinated polymers, liquid crystal materials, and organic electronic materials.

4. Fluorinated Compound Synthesis

Serves as a precursor for the preparation of various fluorinated pharmaceuticals, agrochemicals, and functional materials.
