Description

n-Hexadecyltrimethylammonium Chloride is a high-purity quaternary ammonium compound (QAC) widely recognized for its potent cationic surfactant properties. This material is essential for applications requiring reliable antimicrobial action, phase transfer catalysis, and surface modification. It serves as a critical raw material for manufacturers in the pharmaceutical, personal care, textile, and biotechnology sectors seeking consistent performance and quality assurance.

Application

• Antiseptic & Disinfectant Formulations: A key active ingredient in hospital-grade disinfectants, sanitizers, and antiseptic solutions due to its broad-spectrum biocidal efficacy.
• Pharmaceutical Synthesis & Catalysis: Employed as a versatile phase-transfer catalyst (PTC) in organic synthesis and the production of active pharmaceutical ingredients (APIs).
• Personal Care & Cosmetics: Used as a conditioning agent and preservative in hair care products, skin creams, and other cosmetic formulations.
• Textile & Fabric Softeners: Imparts softness and antistatic properties to fabrics as a primary component in cationic softener formulations.
• Biotechnology & DNA Extraction: Facilitates cell lysis and purification processes in molecular biology for nucleic acid isolation.
• Industrial Water Treatment: Acts as a biocide and algicide in cooling water systems and industrial process water.
• Analytical Chemistry: Serves as an ion-pairing agent in chromatographic techniques like HPLC for separating complex mixtures.
• Nanomaterial Synthesis: Functions as a stabilizing or structure-directing agent in the preparation of nanoparticles and mesoporous materials.

Quality Control

Our n-Hexadecyltrimethylammonium Chloride is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, identity, and performance. A Certificate of Analysis (COA) documenting key parameters such as assay, moisture content, and residue on ignition is provided with each shipment to guarantee traceability and compliance.

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 product 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.
