Description

Butylnaphthalenesulphonic Acid CAS NO 26761-78-4 is a specialized organic sulfonic acid derivative, valued for its strong acidic properties and surfactant characteristics. This compound is a critical intermediate and functional additive in several high-value industrial synthesis and formulation processes. It is primarily sought by manufacturers in the chemical, agrochemical, and material science sectors for its role in catalysis, dispersion, and as a building block for more complex molecules.

Application

• Catalyst and Acid Catalyst Precursor: Used in organic synthesis reactions, including alkylation and esterification, where a strong, soluble organic acid is required.
• Surfactant and Dispersant Intermediate: Serves as a key raw material for manufacturing anionic surfactants, wetting agents, and dispersants for agrochemicals and coatings.
• Electroplating Additive: Employed in electroplating baths to improve bath stability, metal distribution, and surface finish quality.
• Corrosion Inhibitor Formulation: A component in specialty formulations designed to protect metal surfaces in industrial cooling and process water systems.
• Dye and Pigment Intermediate: Acts as a solubilizing and coupling agent in the production of certain dyes and organic pigments.
• Polymerization Aid: Can be used as an emulsifier or catalyst in specific polymerization processes for resins and plastics.

Quality Control

Our Butylnaphthalenesulphonic Acid is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing to ensure consistent purity, chemical identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, moisture content, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and a strong acid/organic solvent; ensure containers are kept tightly sealed to exclude moisture and stored separately from bases and oxidizing agents.
