Description

1-Decylpyridinium Bromide is a quaternary ammonium compound (quat) that serves as a highly effective cationic surfactant and phase-transfer catalyst. This chemical is valued for its ability to facilitate reactions between reagents in immiscible solvents and for its potent antimicrobial and antistatic properties. It is a critical material for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical synthesis sectors seeking reliable, high-purity intermediates.

Application

• Phase-Transfer Catalyst (PTC): Enables and accelerates reactions between ionic and organic reactants in biphasic systems, crucial for alkylation, esterification, and displacement reactions.
• Antimicrobial Agent: Used in the formulation of disinfectants, sanitizers, and preservatives for industrial and institutional applications due to its biocidal activity.
• Surfactant & Emulsifier: Functions as a cationic surfactant in specialty cleaning formulations, textile processing aids, and emulsion polymerization.
• Chemical Synthesis Intermediate: Serves as a key building block for the synthesis of more complex quaternary ammonium compounds and ionic liquids.
• Antistatic Agent: Imparts antistatic properties to plastics, synthetic fibers, and coatings.
• Corrosion Inhibitor: Employed in formulations for metalworking fluids and industrial water treatment to protect metal surfaces.

Quality Control

Our 1-Decylpyridinium Bromide is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay by titration, identification by FT-IR, and determination of key impurities, to ensure it meets precise specifications for purity and performance. Certificates of Analysis (COA) documenting these results are provided with each shipment and are available upon request.

Storage

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