Description

Benzoic Acid, 2-6-(Ethylamino)-3-(Ethylimino)-2,7-Dimethyl-3H-Xanthen-9-Yl-, Ethoxylated, Sulfate (1:1) (Salt) is a specialized xanthene dye derivative, engineered for high-performance applications requiring intense color and stability. This compound matters for its unique combination of a sulfated, ethoxylated structure, which enhances its solubility and compatibility in complex formulations. It is primarily needed by manufacturers in the textile, ink, and specialty coatings industries where precise colorants and functional additives are critical.

Application

• Textile Dyeing and Printing: As a key colorant component for synthetic fibers, providing vibrant and wash-fast hues.
• Industrial Ink Formulation: Used in the production of inks for packaging, security printing, and non-paper substrates.
• Functional Additive for Coatings: Imparts color and can act as a marker or tracer in industrial and protective coatings.
• Research & Development: Serves as a chemical intermediate or reference standard in the synthesis of novel dye molecules and photochemical studies.
• Specialty Chemical Manufacturing: Utilized in the production of color-concentrates and masterbatches for plastics.
