CAS 2303-01-7: m-cresolo porpora

Descrizione:
m-cresolo porpora, con il numero CAS 2303-01-7, è un composto organico sintetico comunemente utilizzato come indicatore di pH in varie applicazioni chimiche e biologiche. È un membro della famiglia dei composti fenolici e si caratterizza per la sua capacità di cambiare colore in risposta a variazioni di pH, passando tipicamente dal giallo in condizioni acide al viola in ambienti alcalini. Questa proprietà lo rende particolarmente utile nelle titolazioni e nel monitoraggio dei livelli di pH in contesti di laboratorio. m-cresolo porpora è solubile in acqua e solventi organici, il che ne aumenta la versatilità in diversi mezzi. Inoltre, ha un profilo di tossicità relativamente basso, rendendolo adatto per l'uso in sistemi biologici. Il composto è spesso utilizzato nella preparazione di soluzioni tampone e nello studio degli equilibri acido-base. Le sue caratteristiche strutturali includono un gruppo cresolo, che contribuisce alle sue proprietà colorimetriche, ed è importante maneggiarlo con cura, seguendo le appropriate linee guida di sicurezza, a causa della sua natura chimica.

  • meta-Cresol Purple

    CAS:
    Meta-Cresol Purple (MCP) is a fluorescent dye that is used to detect DNA polymerase chain reaction products. It is a cationic dye with an absorption maximum of 590 nm in the visible spectrum. MCP has been shown to bind to nucleic acids and therefore can be used as a probe for detecting DNA polymerase chain reaction products. The detection time for MCP can be up to 10 minutes. The biological studies show that MCP binds to the 3' hydroxyl group of the ribose sugar backbone of nucleic acids, which prevents the interaction of MCP with other biomolecules such as proteins. MCP has also been used in urine samples as an antimicrobial agent against bacterial strains like Escherichia coli and Pseudomonas aeruginosa and yeast strains like Candida albicans and Saccharomyces cerevisiae. MCP is soluble in sodium carbonate at neutral pH, but insoluble in water or
