Astrazon Red 6B(CAS: 6441-82-3)

Astrazon Red 6B (CAS: 6441-82-3) is a red azo dye with a molecular weight of approximately 492.42 g/mol. It has a crystalline form with a melting point of about 220°C. The dye is slightly soluble in water and ethanol. It is relatively stable in acidic and neutral solutions but can be oxidized in basic conditions. It is used in textile dyes and paints due to its good light and wash fastness.

Astrazon Red 6B (CAS: 6441-82-3) is synthesized through a multi-step process involving coupling of a substituted aromatic amine with an azo dye precursor. The synthesis involves the use of amines and azo coupling agents under various conditions. The reaction typically requires a strong acid catalyst and is carried out at elevated temperatures. The product is purified and crystallized to obtain the final dye.

Astrazon Red 6B (CAS: 6441-82-3) is widely used in the textile and dyeing industries for coloring fabrics and yarns. It is also used in the paint and coating industry to impart red color. Additionally, it finds applications in the polymer industry, where it can be used as a colorant for polymeric materials. Its stability and light-fastness make it suitable for outdoor applications.

When handling Astrazon Red 6B (CAS: 6441-82-3), it is essential to wear appropriate personal protective equipment (PPE), including gloves, safety goggles, and a lab coat. Work in a well-ventilated area or a fume hood to minimize inhalation risks. Spills should be cleaned up immediately using appropriate absorbent materials. Always refer to the safety data sheet (SDS) for specific handling instructions and emergency procedures.
