Description

Bis-1,7-(Trimethylammonium)Hepyl Dibromide is a high-purity quaternary ammonium salt (quat) surfactant, valued for its potent cationic and antimicrobial properties. This compound is essential for formulators requiring a stable, long-chain dialkyl quat with excellent surface activity and biocidal efficacy. It serves as a critical raw material for industrial disinfectants, fabric softeners, and specialized chemical synthesis where a bifunctional cationic structure is needed.

Application

• Industrial Biocides & Disinfectants: A key active ingredient in formulations for hard surface cleaners, sanitizers, and algaecides due to its broad-spectrum antimicrobial activity.
• Fabric Care & Softening Agents: Used as a cationic softener base in laundry detergents and textile finishing to impart antistatic and softening properties.
• Phase Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases in organic synthesis, particularly for alkylation and displacement reactions.
• Surfactant & Emulsifier: Functions as a cationic surfactant in emulsion polymerization, personal care products, and specialty cleaning formulations.
• Oilfield Chemicals: Employed in drilling muds and completion fluids as a clay stabilizer and bactericide.
• Paper & Pulp Industry: Acts as a retention aid, drainage aid, and biocide in papermaking processes.
• Research & Development: Serves as a biochemical reagent and a building block for synthesizing more complex quaternary ammonium compounds.

Quality Control

Our Bis-1,7-(Trimethylammonium)Hepyl Dibromide is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including assay, identification, and impurity profiling, to ensure it meets precise customer specifications and industry standards. Certificates of Analysis (COA) documenting purity, physical characteristics, and test results are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and stability.
