Description

Bromoethyne CAS NO 593-61-3 is a highly reactive and versatile halogenated acetylene derivative, serving as a critical building block in advanced organic synthesis. Its unique structure, featuring a triple bond adjacent to a bromine atom, makes it an invaluable reagent for introducing the ethynyl group and for cycloaddition reactions. This compound is essential for research chemists and process development scientists in the pharmaceutical, agrochemical, and materials science industries seeking to create novel molecular architectures.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds containing acetylene or heterocyclic moieties.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and plant growth regulators requiring specific alkyne functional groups.
• Material Science Research: Acts as a monomer or cross-linking agent in the development of advanced polymers, conductive materials, and metal-organic frameworks (MOFs).
• Organic Synthesis Reagent: Employed in Huisgen cycloaddition (click chemistry) and other coupling reactions to construct complex organic molecules efficiently.
• Chemical Biology Probes: Utilized for labeling and modifying biomolecules, enabling studies in proteomics and bio-conjugation.
• Ligand Preparation: Serves as a starting material for synthesizing specialized ligands used in catalysis and coordination chemistry.

Quality Control

Our Bromoethyne is produced and handled under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) and Nuclear Magnetic Resonance (NMR) spectroscopy, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are available upon request, supporting your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and reactive nature, store under an inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated area, away from heat, ignition sources, and incompatible materials such as strong acids and oxidizing agents. Recommended storage temperature is 2-8°C for extended stability.
