Description

n-[3-(Dimethylamino)Propyl]-1,1,2,2,3,3,4,4,5,5,6,6,7,7,7-Pentadecafluoroheptane-1-Sulphonamide Monohydrochloride is a specialized fluorinated sulfonamide salt with a tertiary amine hydrochloride moiety. This compound is valued for its unique combination of extreme hydrophobicity and oleophobicity from the perfluoroalkyl chain and the reactive/ionic functionality provided by the sulphonamide and amine hydrochloride groups. It serves as a critical intermediate or functional additive in advanced material science and specialty chemical synthesis, where surface modification and specific chemical reactivity are required.

Application

• Fluorinated Surfactant & Surface Modifier: Key component for creating ultra-low surface energy coatings, water- and oil-repellent finishes for textiles, and anti-fouling surfaces.
• Pharmaceutical & AgroChemical Intermediate: Used in the synthesis of novel active ingredients that require enhanced bioavailability, metabolic stability, or membrane permeability.
• Specialty Polymer Additive: Imparts stain resistance, chemical inertness, and improved processing characteristics to high-performance polymers and elastomers.
• Lithium-Ion Battery Electrolyte Additive: Potential application in forming stable solid-electrolyte interphase (SEI) layers to improve battery cycle life and safety.
• Advanced Material Research: Building block for self-assembled monolayers (SAMs), liquid crystals, and other nanostructured materials with tailored interfacial properties.
• Firefighting Foam Formulations (Legacy/Research): Historically related to fluorosurfactant chemistry used in aqueous film-forming foams (AFFFs) for fuel fires.

Quality Control

Our n-[3-(Dimethylamino)Propyl]-1,1,2,2,3,3,4,4,5,5,6,6,7,7,7-Pentadecafluoroheptane-1-Sulphonamide Monohydrochloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing including HPLC, NMR, and titration to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key specifications such as assay, impurity profile, and moisture content.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product stability and performance. Keep away from incompatible materials such as strong bases and oxidizing agents.
