For laboratory professionals, understanding the fundamental properties of the chemicals they use daily is key to ensuring accuracy and efficiency. Phenol Red, a compound widely recognized by its CAS number 143-74-8, is a prime example of such an essential laboratory chemical. Primarily known for its role as a pH indicator, Phenol Red provides a visual and straightforward method for determining the acidity or alkalinity of a solution. Its distinct color change, from yellow to red within a specific pH range, makes it a staple in countless analytical procedures and research settings. If you are in need of reliable Phenol Red for your laboratory work, NINGBO INNO PHARMCHEM CO.,LTD. is a leading supplier in China ready to meet your requirements.

The chemical makeup of Phenol Red, with the molecular formula C19H14O5S, contributes to its chromophoric properties, allowing it to absorb and reflect light in a way that produces visible color. In aqueous solutions, Phenol Red exists in different ionic forms depending on the pH. Below pH 6.6, it predominantly exists in its protonated form, which appears yellow. As the pH increases towards 8.0, it undergoes a structural change, becoming deprotonated and exhibiting a vibrant red hue. This predictable transition makes it an excellent tool for titrations and for monitoring chemical reactions where pH control is critical. Many researchers choose to buy Phenol Red because of this reliable and easily observable color shift.

The applications of Phenol Red extend significantly into the biological sciences, particularly in cell culture. In this context, Phenol Red acts as a visual pH monitoring system for the growth medium. As cells consume nutrients and release metabolic waste products, the pH of the culture medium can change. Typically, this leads to an increase in acidity, causing the red medium to turn yellow. This visual cue alerts scientists to potential issues with the cell culture, such as contamination or the need for a medium change, thereby supporting cell viability and proliferation studies. The consistent performance of Phenol Red is crucial for the success of these sensitive experiments, emphasizing the need to source from reputable manufacturers like NINGBO INNO PHARMCHEM CO.,LTD.
