Description

Sodium 3-Amino-4-(Methyloctadecylamino)Benzenesulphonate is a specialized anionic surfactant and dye intermediate characterized by its unique long-chain alkylamino substituent. This molecular structure provides excellent surface-active properties and compatibility with hydrophobic systems, making it a valuable functional additive. It is primarily utilized in the production of high-performance dyes, pigments, and as a specialty surfactant in industrial formulations where specific wetting and dispersing actions are required.

Application

• Dye and Pigment Intermediate: A key building block in the synthesis of oil-soluble azo dyes and complex organic pigments.
• Specialty Surfactant: Used in formulations requiring emulsification, wetting, or dispersion of hydrophobic materials in aqueous systems.
• Textile Auxiliary: Functions as a leveling agent or dispersant in dye baths for synthetic fibers.
• Ink Manufacturing: Employed to improve the stability and rheological properties of industrial and printing inks.
• Oilfield Chemicals: Potential application as a component in drilling mud additives or corrosion inhibitors.
• Research & Development: Serves as a standard or reagent in chemical research for developing new surfactants and functional materials.

Quality Control

Our products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Quality parameters are strictly monitored through modern analytical techniques including HPLC, IR spectroscopy, and titration methods. A Certificate of Analysis (COA) detailing purity, identity, and specific impurity profiles is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect product quality and flow properties. Keep away from strong oxidizing agents.
