1-Naphthalenesulfonic acid, 4-[[diamino(1-naphthalenylazo)phenyl]azo]-, monosodium salt

Description:

1-Naphthalenesulfonic acid, 4-[[diamino(1-naphthalenylazo)phenyl]azo]-, monosodium salt, commonly referred to as a dye intermediate, is characterized by its azo structure, which consists of two aromatic rings connected by an azo (-N=N-) linkage. This compound typically appears as a dark-colored solid or powder and is soluble in water due to the presence of the sulfonic acid group, which enhances its ionic character. The presence of amino groups contributes to its reactivity, making it useful in dye synthesis and as a colorant in various applications, including textiles and food. Its sodium salt form indicates that it can dissociate in solution, releasing sodium ions. The compound is known for its stability under normal conditions but may undergo degradation when exposed to strong acids or bases. Safety considerations include potential skin and eye irritation, and it is advisable to handle it with appropriate protective measures. Overall, this compound plays a significant role in the dye industry due to its vibrant color and chemical properties.
