CAS 76-60-8: Vert de bromocrésol
Description :
Vert de bromocrésol est un colorant synthétique et un indicateur de pH couramment utilisé dans diverses applications biochimiques. Il se caractérise par sa capacité à changer de couleur en réponse à des variations de pH, passant généralement du jaune en conditions acides au bleu en environnements alcalins, avec une plage de transition de pH autour de 3,8 à 5,4. Cette propriété le rend précieux dans les titrations et comme colorant biologique. D'un point de vue chimique, Vert de bromocrésol est un dérivé de phénol sulfoné, et sa structure moléculaire comprend des atomes de brome, qui contribuent à ses propriétés colorimétriques. Il est soluble dans l'eau et présente un spectre d'absorption distinct, ce qui le rend utile dans les analyses spectrophotométriques. De plus, Vert de bromocrésol est souvent utilisé dans les laboratoires microbiologiques et cliniques pour la détection de certains micro-organismes et dans l'évaluation des concentrations de protéines. Bien qu'il soit généralement considéré comme sûr pour une utilisation en laboratoire, il est important de le manipuler avec précaution, comme toutes les substances chimiques, pour éviter d'éventuels risques pour la santé.

CAS :Bromocresol green is a cationic surfactant that is used as a fluorescent indicator dye. It binds to proteins and can be detected with an optical sensor. Bromocresol green has been shown to react with hydrochloric acid, which may be due to the protonation of the cationic group. This reaction is reversible and depends on pH. The binding of bromocresol green to serum proteins results in a decrease in fluorescence intensity due to quenching by adsorption at the protein-protein interface. The kinetic data for this dye have been found to depend on α1-acid glycoprotein concentration.Formule :C21H14Br4O5SCouleur et forme :PowderMasse moléculaire :698.01 g/mol
