Description

3-Amino-4-(Tetradecyloxy)Benzenesulphonic Acid is a specialized organic intermediate featuring a long-chain alkoxy group attached to an aminosulfonic acid aromatic core. This unique molecular structure makes it a valuable building block for synthesizing surfactants, dyes, and functional materials with specific hydrophobic and hydrophilic properties. It is primarily sought by manufacturers in the specialty chemical, surfactant, and advanced material sectors for research and production scale applications.

Application

• Surfactant Intermediate: A key precursor for the synthesis of anionic surfactants with long hydrophobic tails, used in industrial cleaners, textile processing, and emulsion polymerization.
• Dye and Pigment Synthesis: Serves as a coupling agent or functional intermediate in the production of oil-soluble dyes, pigments, and colorants.
• Lubricant Additive: Used in the formulation of specialty lubricants and fuel additives where surface-active properties are required.
• Chemical Research (R&D): Employed as a building block in organic synthesis and material science for developing novel compounds with tailored properties.
• Corrosion Inhibitor Formulation: Acts as a component in formulations designed to protect metals in harsh environments.
• Pharmaceutical Intermediate: Potential use in the synthesis of active pharmaceutical ingredients (APIs) or excipients requiring specific solubility profiles.
