CAS 34487-61-1

Phenol red sodium

Description:

Phenol red sodium, with the CAS number 34487-61-1, is a pH indicator commonly used in various biological and chemical applications. It appears as a reddish-brown powder or crystalline solid and is soluble in water, exhibiting a color change from yellow to red as the pH transitions from acidic to slightly alkaline conditions, typically around pH 6.8 to 8.4. This property makes it valuable in cell culture media and laboratory experiments to monitor pH changes. Phenol red sodium is non-toxic and is often used in medical diagnostics and as a biological stain. Additionally, it has applications in the food industry as a color additive. Its chemical structure consists of a phenolic group, which contributes to its acidic properties, and it is classified as a weak acid. Care should be taken when handling this compound, as with any chemical, to ensure safety and proper disposal.

Phenol red sodium salt

CAS: 34487-61-1

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.

Controlled Product

CAS: 34487-61-1

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. It can also be used as reactant/reag
