Description

Tetradodecylammonium Chloride is a high-purity quaternary ammonium salt (quat) with the CAS registry number 82944-72-7, valued for its potent cationic surfactant properties. This compound is essential for applications requiring stable, long-chain ammonium-based activity, offering excellent phase-transfer catalysis and antimicrobial efficacy. It is a critical raw material for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical synthesis sectors.

Application

• Phase-Transfer Catalyst (PTC): A highly effective catalyst for reactions between reagents in immiscible phases, particularly in alkylation, esterification, and polymerization processes.
• Antimicrobial Agent: Used in the formulation of industrial biocides, disinfectants, and preservatives for its broad-spectrum activity against bacteria and fungi.
• Surfactant & Emulsifier: Serves as a cationic surfactant in specialty emulsions, fabric softeners, and asphalt additives due to its strong surface-active properties.
• Chemical Synthesis Intermediate: Acts as a key building block or reagent in organic synthesis for producing more complex quaternary ammonium compounds.
• Analytical Chemistry: Employed in ion-pair chromatography as a pairing agent to separate and analyze acidic compounds.
• Corrosion Inhibition: Formulated into corrosion inhibitors for industrial water treatment and oilfield applications.

Quality Control

Our Tetradodecylammonium Chloride is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. A comprehensive Certificate of Analysis (COA) documenting assay, impurity profile, and physical characteristics is provided with each shipment to guarantee consistency and 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); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
