Description

Trisodium 1-[4-[[4-[bis[2-[(2-chloroethyl)sulphonyl]ethyl]amino]-6-chloro-1,3,5-triazin-2-yl]amino]-2-sulphonatophenyl]-4,5-dihydro-5-oxo-4-[(2-sulphonatophenyl)azo]-1H-pyrazole-3-carboxylate is a high-purity, reactive dye intermediate of significant commercial importance. This compound is valued for its role in synthesizing high-performance, wash-fast reactive dyes, particularly for cellulosic fibers like cotton. It is essential for manufacturers and R&D facilities in the textile, specialty chemical, and advanced materials sectors seeking to develop vibrant and durable colorants.

Application

This advanced chemical intermediate is primarily utilized in the synthesis of high-value reactive dyes. Its specific applications include:

• Primary intermediate for fiber-reactive dyes used in textile dyeing and printing.
• Key component in the manufacture of dyes for cotton, viscose, and other cellulosic fibers.
• Used in R&D for developing novel chromophores with enhanced light and wash fastness properties.
• Potential use in the synthesis of functional dyes for non-textile applications, such as inks or specialty coatings.
• Serves as a building block in organic synthesis for complex heterocyclic and azo compounds.

Quality Control

Our production of this reactive dye intermediate adheres to strict quality management protocols to ensure batch-to-batch consistency and high purity. The material is characterized using advanced analytical techniques including HPLC, NMR, and mass spectrometry. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory needs.

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 compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product stability and performance.
