Description

Bis(2,4-Dichlorobenzyl)Dimethylammonium Chloride is a quaternary ammonium salt (quat) compound valued for its potent antimicrobial and surfactant properties. This chemical is a critical intermediate and active ingredient in the formulation of high-performance disinfectants, sanitizers, and industrial biocides. It is essential for manufacturers in the hygiene, water treatment, and material preservation sectors seeking effective and stable active agents.

Application

• Disinfectant & Sanitizer Formulations: Serves as a key active ingredient in hospital-grade disinfectants, surface cleaners, and hand sanitizers.
• Industrial Biocides: Used in cooling water systems, pulp and paper processing, and oilfield operations to control microbial growth.
• Algaecides & Fungicides: Effective in controlling algae and fungi in recreational water, agricultural settings, and construction materials.
• Textile & Leather Treatment: Imparts antimicrobial properties to fabrics, leather goods, and technical textiles.
• Preservative for Paints & Coatings: Prevents spoilage in water-based formulations and provides in-can and dry-film protection.
• Personal Care Products: Incorporated as a preservative in certain rinse-off cosmetic and personal care formulations.

Quality Control

Our Bis(2,4-Dichlorobenzyl)Dimethylammonium Chloride is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for assay and impurity profiling, to ensure high purity and consistent performance. Certificates of Analysis (COA) documenting full specifications are provided with each shipment 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 may affect quality.
