CAS 34487-61-1
:Rosso fenolo sodico
Descrizione:
Rosso fenolo sodico, con il numero CAS 34487-61-1, è un indicatore di pH comunemente usato in varie applicazioni biologiche e chimiche. Si presenta come una polvere o un solido cristallino di colore marrone rossastro ed è solubile in acqua, mostrando un cambiamento di colore da giallo a rosso man mano che il pH passa da condizioni acide a leggermente alcaline, tipicamente intorno a pH 6,8 a 8,4. Questa proprietà lo rende prezioso nei mezzi di coltura cellulare e negli esperimenti di laboratorio per monitorare i cambiamenti di pH. Rosso fenolo sodico è non tossico ed è spesso utilizzato nella diagnostica medica e come colorante biologico. Inoltre, ha applicazioni nell'industria alimentare come additivo colorante. La sua struttura chimica consiste in un gruppo fenolico, che contribuisce alle sue proprietà acide, ed è classificato come un acido debole. Si deve prestare attenzione quando si maneggia questo composto, come con qualsiasi sostanza chimica, per garantire la sicurezza e lo smaltimento corretto.

CAS:<p>Phenol red is a pH indicator that finds broad applications from chemistry to microbiology. Colour varies from yellow at pH<6.8 (lmax 443nm) through to light red/pink at 6.8<pH<8.2 (lmax 570 nm) to vivid purple/red at pH>8.2. It is widely used in cell culture to monitor pH and for colorimetric titration. For example, phenol red can be used to quantify Br- content in sea or fresh water. It is added to VTM as pH indicator, at the concentration of 10mg/ml, maintaining a pink colour at neutral pH.</p>Formula:C19H13NaO5SColore e forma:Slightly Brown Red PowderPeso molecolare:376.36 g/molPhenol Red Sodium Salt ACS (water soluble), 95%

CAS:Prodotto controllato<p>Applications Phenol Red Sodium Salt is a water soluble pH indicator commonly employed in cell biology laboratories as a cell tissue culture pH marker. Phenol Red sodium salt is a water soluble pH indicator used in the 6.8 (yellow) to 8.2 (red) range. It is commonly employed in cell biology laboratories as a cell tissue culture pH marker. Under normal conditions, phenol red added to the growth medium will have a pink-red color. Usually 15 mg/l is used to produce this effect. If problems arise, such as dying cells or overgrowth of contaminants, this will cause a change in pH resulting in a change in indicator color. This color change is an indication that the medium needs to be replaced. Additionally, Phenol Red could potentially be useful as a differentiation factor.
