CAS 13301-61-6

Disperse Orange 37

Description:

Disperse Orange 37, with the CAS number 13301-61-6, is a synthetic organic dye primarily used in the dyeing of synthetic fibers, particularly polyester. It belongs to the class of disperse dyes, which are characterized by their ability to be dispersed in water for application on hydrophobic substrates. This dye exhibits a bright orange hue and is known for its good lightfastness and washfastness properties, making it suitable for textile applications. Chemically, Disperse Orange 37 is an azo dye, which means it contains an azo group (-N=N-) that contributes to its color properties. The dye is typically applied in a dispersed form, requiring specific conditions such as elevated temperatures to facilitate the dyeing process. While it is effective for coloring textiles, safety considerations are important, as some azo dyes can release aromatic amines that may pose health risks. Therefore, handling and disposal should be conducted with care, adhering to relevant safety regulations.

C.I.Disperse Orange 76

CAS: 13301-61-6

C.I.Disperse Orange 76 (CIDO76) is a photostable, fluorescent dye that is used as a particle marker in analytical chemistry and other fields. It has shown to be genotoxic and carcinogenic in animal models, but the clinical relevance of these findings is unclear. CIDO76 can be prepared by reacting amines with diazonium salt, which produces azo dyes. It is also used as an optical sensor for thermally activated reactions and can be detected using chromatographic methods. CIDO76 emits light at 675 nm when irradiated with ultraviolet light, which makes it useful for many applications including wastewater treatment and detection of model systems.
