Description

Bromocyclopentane CAS NO 137-43-9 is a versatile halogenated organic compound, primarily used as a key alkylating agent and intermediate in advanced organic synthesis. Its value lies in the reactivity of the bromine atom, which facilitates efficient carbon-carbon bond formation and functional group transformations under controlled conditions. This makes it an essential building block for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries.

Application

• Pharmaceutical Intermediate: Serves as a crucial precursor in the synthesis of active pharmaceutical ingredients (APIs) and complex drug molecules.
• Agrochemical Synthesis: Used in the production of pesticides, herbicides, and other crop protection agents.
• Organic Synthesis Reagent: Acts as an alkylating agent in Grignard reactions, nucleophilic substitutions, and cross-coupling reactions (e.g., Suzuki, Negishi).
• Material Science Research: Employed in the development of novel polymers, liquid crystals, and advanced organic materials.
• Chemical Intermediate: A foundational building block for synthesizing more complex cyclopentane-derived compounds in fine chemical production.
• Laboratory Research & Development: Utilized in academic and industrial R&D settings for method development and exploratory chemistry.
