Mordant Orange 1

Description:

Mordant Orange 1, with the CAS number 2243-76-7, is an organic dye belonging to the azo dye family, characterized by its vibrant orange color. It is primarily used in textile dyeing, particularly for wool and silk, due to its ability to form strong complexes with metal ions, which enhances its colorfastness. The dye exhibits good solubility in water, making it suitable for various dyeing processes. Mordant Orange 1 is known for its stability under light and heat, although, like many azo dyes, it may undergo degradation under extreme conditions. Its chemical structure typically includes azo (-N=N-) linkages, which are responsible for its color properties. Safety considerations are important, as some azo dyes can release aromatic amines, which may pose health risks. Therefore, handling Mordant Orange 1 requires adherence to safety guidelines to minimize exposure. Overall, it is a valuable dye in the textile industry, appreciated for its bright hue and durability when properly applied.

Mordant Orange 1

CAS: 2243-76-7

Mordant Orange 1 is a water-soluble polymeric dye that has been shown to be an effective chelator for metal ions. It has been used in wastewater treatment, as well as in human serum, to remove hydrophobic substances. Mordant Orange 1 binds to the metal ions and prevents them from reacting with the biological system. The binding of Mordant Orange 1 can be demonstrated using electrochemical impedance spectroscopy on a flow cell. It is also capable of removing yellow coloration from textile fibers. This dye also binds to alizarin, which is a red dye that can be found in plants such as madder and rhubarb. This binding mechanism is due to hydrogen bonds and amine groups present on the surface of Mordant Orange 1 (see below).
