Description

Benzenesulfonic acid, 2-5-(aminocarbonyl)-1-ethyl-1,6-dihydro-2-hydroxy-4-methyl-6-oxo-3-pyridinylazo-4-(4-amino-6-chloro-1,3,5-triazin-2-yl)amino-5-4-2-(sulfooxy)ethylsulfonylphenylazo-, sodium salt is a high-performance, water-soluble reactive dye intermediate characterized by its complex polyazo and triazine-based structure. This compound is engineered to provide exceptional color strength and covalent bonding properties to substrates, ensuring superior wash and light fastness in the final dyed product. It is a critical raw material for manufacturers of reactive dyes targeting the textile, leather, and specialty paper industries, where consistent quality and reliable supply are paramount for production efficiency.

Application

• Reactive Dye Synthesis: Primary intermediate for manufacturing high-grade reactive dyes for cellulose fibers like cotton, viscose, and linen.
• Textile Industry: Used in the production of dyes for exhaust, pad-batch, and continuous dyeing processes, offering brilliant shades and excellent fixation.
• Leather Coloring: Key component in formulating dyes for leather finishing, providing deep, uniform coloration with good fastness properties.
• Paper Dyeing: Employed in the manufacture of dyes for specialty and high-quality paper products requiring vibrant and stable colors.
• Ink Formulation: Serves as a colorant precursor in certain industrial ink systems where water solubility and reactivity are beneficial.
• Research & Development: Utilized in chemical R&D for developing new chromophores and studying dye-polymer interactions.

Quality Control

Our Benzenesulfonic acid derivative is produced under a stringent quality management system to ensure batch-to-batch consistency and purity. Each lot is analyzed against rigorous in-house specifications, which typically include parameters for assay (HPLC), impurity profile, and color strength. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is kept tightly sealed to prevent absorption of atmospheric moisture, which may affect performance.
