Rosso clorofenolo

Descrizione:

Rosso clorofenolo è un composto organico comunemente usato come indicatore di pH in varie applicazioni chimiche. È caratterizzato dalla sua capacità di cambiare colore in risposta alle variazioni di pH, passando tipicamente dal giallo a pH acidi al rosso in condizioni più alcaline. Questa proprietà lo rende prezioso in ambienti di laboratorio per monitorare i cambiamenti di pH nelle soluzioni. Rosso clorofenolo è un colorante sintetico e la sua struttura chimica include un gruppo fenolico, che contribuisce alle sue proprietà acide. È solubile in acqua e mostra una buona stabilità in condizioni normali, anche se può degradarsi in condizioni estreme di pH o temperatura. Oltre al suo utilizzo negli indicatori di pH, Rosso clorofenolo può anche servire come colorante biologico ed è utilizzato in saggi microbiologici. Devono essere osservate precauzioni di sicurezza quando si maneggia questo composto, poiché può comportare rischi per la salute se ingerito o inalato. In generale, Rosso clorofenolo è un chimico versatile e ampiamente utilizzato sia in applicazioni di ricerca che industriali.

Chlorophenol red

CAS: 4430-20-0

Chlorophenol red is a fluorescent probe that can be used in the detection of microbial infection. It has been shown to react with malonic acid (MAA) and fluoresce at an excitation wavelength of ~480 nm and emission wavelength of ~520 nm. The linear calibration curve for this assay was generated using human serum, which is a good model system for detecting infectious diseases. Chlorophenol red was also shown to bind to the receptor activity on mammalian cells and can be used as a marker for autoimmune diseases.
