1-Naphthalenesulfonic acid, 4,4′-[(2,4-dihydroxy-1,3-phenylene)bis(2,1-diazenediyl)]bis-, sodium salt (1:2)

Description:

1-Naphthalenesulfonic acid, 4,4′-[(2,4-dihydroxy-1,3-phenylene)bis(2,1-diazenediyl)]bis-, sodium salt (1:2), commonly referred to as a dye or pigment, is a complex organic compound characterized by its sulfonic acid group and azo linkages. This compound typically appears as a dark-colored solid or powder and is soluble in water, which enhances its utility in various applications, particularly in dyeing processes. The presence of the naphthalene and phenylene structures contributes to its chromophoric properties, making it effective as a colorant. Its sodium salt form indicates that it is ionized, which can improve its solubility and stability in aqueous solutions. This compound is often used in textiles, paper, and other materials where vibrant coloration is desired. Additionally, it may exhibit properties such as lightfastness and resistance to fading, depending on the specific formulation and application conditions. Safety data should be consulted, as with all chemical substances, to ensure proper handling and usage.
