Understanding pH Indicators: The Role of Phenol Red in Your Lab
In the realm of chemistry and biology, precise measurement and control of pH are paramount. Whether you are conducting delicate titrations in an analytical chemistry lab or nurturing cell cultures, understanding the pH of your solution is crucial. This is where pH indicators come into play, and one of the most widely recognized and utilized is Phenol Red. With its characteristic color change, Phenol Red offers a clear visual cue for pH shifts, making it an indispensable tool for researchers and chemists alike. If you are looking to buy Phenol Red or seek a reliable supplier for your laboratory needs, NINGBO INNO PHARMCHEM CO.,LTD. is your trusted source.
Phenol Red, identified by its CAS number 143-74-8, is a sulfonphthalein dye that exhibits a distinct color transition. It typically appears as a red solid. Its primary function is as a pH indicator, changing from yellow in acidic conditions to red in alkaline conditions. The transition range is generally accepted to be between pH 6.6 (yellow) and pH 8.0 (red). This specific range makes it particularly useful for monitoring processes that occur around neutral pH, a common scenario in many biological and chemical applications. The ability to easily ascertain whether a solution is acidic, neutral, or alkaline through a simple visual color check is invaluable, saving time and reducing the need for electronic pH meters in certain contexts.
The versatility of Phenol Red extends beyond basic laboratory titrations. In biological research, it is frequently incorporated into cell culture media. Here, it serves a dual purpose: indicating the metabolic state of the cells and monitoring the pH of the culture environment. As cells metabolize, they often produce acidic byproducts, which can lower the pH of the medium. The change in Phenol Red's color from red to yellow signals this drop in pH, alerting researchers that the medium may need to be replenished or changed to maintain optimal conditions for cell growth and viability. This proactive monitoring is key to achieving reproducible results in cell culture experiments. For those seeking to buy Phenol Red for these advanced applications, ensuring high purity and consistent performance is vital.
