Descrição:

Ácido 2-naftalenossulfônico, 6-[2-[2-amino-4-[(2-hidroxietil)amino]fenil]diazenil]-3-[2-[4-[[4-[2-[7-[2-[2-amino-4-[(2-hidroxietil)amino]fenil]diazenil]-1-hidroxi-3-sulfo-2-naftalenil]diazenil]fenil]amino]-3-sulfofenil]diazenil]-4-hidroxi-, sal de sódio (1:3), comumente referido pelo seu número CAS 6428-38-2, é um composto orgânico complexo caracterizado por sua estrutura de corante azoico. Esta substância apresenta múltiplos grupos funcionais, incluindo grupos ácido sulfônico e amino, que contribuem para sua solubilidade em água e potenciais aplicações em tingimento e como indicador de pH. A presença de anéis de naftaleno e fenilo em sua estrutura sugere que pode exibir fortes propriedades colorantes, tornando-a útil em várias aplicações industriais, particularmente em têxteis e tintas. Além disso, a forma de sal de sódio do composto melhora sua estabilidade e solubilidade em soluções aquosas. Sua estrutura intrincada também pode indicar uma potencial atividade biológica, justificando uma investigação mais aprofundada sobre seus impactos ambientais e na saúde.

C.I.Direct black 32

CAS: 6428-38-2

C.I.Direct Black 32 is a diazonium salt with an average particle diameter of about 10 nm and a dichroic ratio of about 1.5. It is used in the manufacture of organic colorants, such as black, brown, blue, and green pigments. C.I.Direct Black 32 has been used as a model species to study the chemical reaction rate of small particles in solution and the kinetics of thermal decomposition of intramolecular hydrogen bonds in polyphenols at various temperatures. The material can be recycled by dissolving it in an organic solvent and precipitating it out with water or uv irradiation.br> C.I.Direct Black 32 has strong absorption properties in the ultraviolet region (UV) and is used for coloring plastics, paper products, textiles, printing ink, leathers, etc.br>
