Description

Tetrasodium 3-[[4-[[8-[[1-[(Anilino)Carbonyl]-2-Oxopropyl]Azo]-1-Hydroxy-3,6-Disulphonato-2-Naphthyl]Azo]Naphthyl]Azo]Naphthalene-1,5-Disulphonate is a high-purity, water-soluble azo dye intermediate characterized by its multiple sulfonate groups, which impart excellent solubility and substantivity. This compound is valued for its role as a critical precursor in the synthesis of high-performance, colorfast dyes and pigments. It is essential for manufacturers in the textile, ink, and specialty chemical industries seeking to produce vibrant and durable colors.

Application

• Primary Intermediate for Reactive Dyes: A key building block in the manufacture of reactive dyes for cotton, wool, and nylon, providing excellent wash and light fastness.
• Direct Dye Synthesis: Used in the production of direct dyes for paper coloring and textile applications requiring high affinity to cellulose fibers.
• Pigment Manufacturing: Serves as a precursor for lake pigments and other high-performance colorants used in inks, paints, and plastics.
• Specialty Chemical Intermediate: Employed in research and development for creating novel chromophores and functional dyes with specific optical properties.
• Biological Staining Agent Precursor: Potential use in the synthesis of stains for histological and cytological applications in laboratory settings.

Quality Control

Our production of this azo dye intermediate adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity. Quality is verified through advanced analytical techniques including HPLC, UV-Vis spectroscopy, and titration methods. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory compliance 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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect product performance and handling.
