Description

1-Bromo(1,2,2,5,5-2H5)Cyclopentane is a deuterated derivative of bromocyclopentane, where five hydrogen atoms are replaced with deuterium, a stable hydrogen isotope. This isotopic labeling is critical for applications requiring precise molecular tracking and reduced metabolic interference. It is primarily utilized by researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors for use as a stable isotope-labeled intermediate or analytical standard.

Application

• Pharmaceutical Research & Development: Serves as a deuterated building block in the synthesis of novel Active Pharmaceutical Ingredients (APIs) for drug discovery and metabolic studies.
• Analytical Chemistry & Metabolomics: Used as an internal standard in mass spectrometry (MS), liquid chromatography-mass spectrometry (LC-MS), and nuclear magnetic resonance (NMR) for accurate quantification and metabolite identification.
• Agrochemical Development: Employed in the synthesis of deuterium-labeled pesticides or herbicides to study environmental fate, degradation pathways, and bioaccumulation.
• Material Science: Acts as a precursor in the development of specialty polymers or organic electronic materials where isotopic purity can influence physical properties.
• Mechanistic Studies: Utilized in kinetic isotope effect (KIE) studies to elucidate reaction mechanisms and pathways in organic synthesis.
