Description

(2-Bromoethyl)Trimethylammonium Bromide is a versatile quaternary ammonium salt with a reactive bromoethyl side chain. This compound is valued as a key chemical intermediate for introducing a positively charged trimethylammonium group into target molecules. It is primarily needed by researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries for applications ranging from drug synthesis to the creation of functional materials and phase-transfer catalysts.

Application

• Pharmaceutical Intermediate: Used in the synthesis of cholinergic agents, muscle relaxants, and other active pharmaceutical ingredients (APIs) requiring a quaternary ammonium moiety.
• Agrochemical Synthesis: Serves as a building block for creating cationic surfactants and plant growth regulators with specific biological activity.
• Phase-Transfer Catalyst (PTC) Precursor: Acts as a starting material for synthesizing specialized quaternary ammonium salts used to facilitate reactions between immiscible reactants.
• Polymer Modification: Employed to introduce permanent cationic charges into polymers for applications in water treatment, flocculation, or as ion-exchange resins.
• Bioconjugation & Protein Labeling: Utilized in biochemical research to alkylate proteins, nucleic acids, or other biomolecules, enabling labeling or functionalization.
• Surface Activator: Used to modify material surfaces to impart cationic characteristics, improving adhesion or antimicrobial properties.
• Research & Development: A valuable reagent in organic synthesis laboratories for constructing complex molecules with quaternary ammonium centers.

Quality Control

Our (2-Bromoethyl)Trimethylammonium Bromide is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by IR and NMR spectroscopy, to ensure it meets stringent specifications for research and industrial use. A Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and batch-to-batch consistency.

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 sealed to prevent absorption of atmospheric moisture, which can affect product stability and handling properties.
