Acid Red 26 (>80%)(CAS: 3761-53-3)

Acid Red 26 (>80%) (CAS: 3761-53-3) is a water-insoluble, light-fast azo dye. It has a molecular weight of approximately 660.4 g/mol. The dye exhibits poor solubility in water but can dissolve in organic solvents. It is stable under acidic conditions and exhibits good resistance to light and fading. Its crystalline form is an amorphous solid. It is reactive towards cellulose and protein fibers, making it suitable for dyeing textiles and leather.

Acid Red 26 (>80%) (CAS: 3761-53-3) is synthesized via the coupling of a 4-aminobenzenesulfonic acid derivative with a disazo coupling component. The reaction is conducted in the presence of a strong acid catalyst such as sulfuric acid. The process is selective and yields a high percentage of the desired product. The typical yield is around 80-90%.

Acid Red 26 (>80%) (CAS: 3761-53-3) is widely used in the textile and leather dyeing industry for its excellent lightfastness and color stability. It is also utilized in the paper industry for coloring paper products. Additionally, it has applications in the plastics and coatings industry, where it can impart vibrant colors to polymer matrices. In the pharmaceutical industry, it may be used as a reference compound for certain tests.

When handling Acid Red 26 (>80%) (CAS: 3761-53-3), it is essential to wear personal protective equipment (PPE) such as gloves, goggles, and protective clothing to prevent skin contact and eye irritation. Work in a well-ventilated area or under a fume hood to avoid inhalation. Spills should be handled promptly using an appropriate absorbent material. Refer to the Safety Data Sheet (SDS) for detailed handling and storage instructions.
