Description

n-Methyl-n-3-Sulfobenzylaniline CAS NO 6387-18-4 is a specialized organic intermediate featuring a sulfonated benzyl group attached to a methylated aniline core. This unique structure makes it a valuable building block for synthesizing dyes, pigments, and functional materials where water solubility and specific electronic properties are required. It is primarily sought after by manufacturers in the fine chemical, specialty dye, and advanced material research sectors.

Application

• Key intermediate in the synthesis of acid dyes and reactive dyes for textiles.
• Building block for pigments used in inks, coatings, and plastics.
• Precursor for sulfonated polymers and ion-exchange resins.
• Intermediate in pharmaceutical and agrochemical research for introducing sulfonate functionality.
• Used in the production of optical brighteners and fluorescent whitening agents.
• Research chemical for developing novel surfactants and dispersants.

Quality Control

Our n-Methyl-n-3-Sulfobenzylaniline is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing specifications such as assay, impurity profile, and physical characteristics is provided and available upon request to support your quality assurance protocols.

Storage

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