Description

n-(2-Bromoethyl)-N,n-Dimethyl-2-Propyn-1-Aminium Bromide is a specialized quaternary ammonium salt with a reactive bromoethyl and propargyl group, making it a valuable bifunctional building block in advanced organic synthesis. Its primary commercial value lies in its ability to act as a versatile linker or precursor for constructing complex molecular architectures, particularly in pharmaceutical and material science research. This compound is essential for R&D chemists and process development teams in the fine chemical, pharmaceutical intermediate, and agrochemical sectors seeking to introduce cationic or reactive handles into target molecules.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of active pharmaceutical ingredients (APIs), especially those requiring quaternary ammonium or propargyl functionalities.
• Bioconjugation & Probe Synthesis: Used as a linker molecule for attaching fluorescent dyes, drugs, or other payloads to biomolecules via click chemistry (utilizing the alkyne group) or alkylation reactions.
• Material Science & Polymer Chemistry: Acts as a monomer or cross-linking agent for creating functional polymers, ionic liquids, or surface-modifying agents with specific cationic properties.
• Agrochemical Research: Employed in the development of novel herbicides, fungicides, or plant growth regulators that incorporate quaternary ammonium structures.
• Catalyst & Ligand Preparation: Useful for synthesizing specialized ligands or phase-transfer catalysts used in asymmetric synthesis and other catalytic processes.
• Academic & Industrial R&D: A critical tool for methodological development in organic chemistry, enabling new routes to complex nitrogen-containing heterocycles and functional materials.

Quality Control

Our n-(2-Bromoethyl)-N,n-Dimethyl-2-Propyn-1-Aminium Bromide is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure it meets the high standards required for research and process chemistry. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, identity, and impurity profiles to support your quality and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from incompatible materials.
