Understanding the Chemical Compound with CAS Number 139-07-1

The study of chemical compounds is vital in various fields such as chemistry, biology, and pharmacology. One such compound that intrigues researchers is the chemical identified by the CAS number 139-07-1, commonly known as phenol red. This article seeks to delve into its properties, uses, and significance in different applications.

Phenol red, chemically denoted as 4-[(2-hydroxy-1-naphthalenyl)azo]benzenesulfonic acid, is a pH indicator that changes color based on the acidity or alkalinity of the solution it is in. At acidic pH levels (below 6.8), phenol red appears yellow, whereas in neutral solutions, it transitions to a reddish color, and at alkaline pH values (above 8.4), it exhibits a bright fuchsia hue. This characteristic makes it a valuable tool in laboratories for monitoring pH levels in various chemical reactions and biological assays.

In terms of molecular structure, phenol red has a complex configuration featuring both aromatic and sulfonic acid groups. Its molecular formula is C19H14N2O5S, and it is highly soluble in water, which further enhances its utility in biological applications. The compound’s ability to undergo reversible color changes makes it an ideal choice for use in cell culture media, where maintaining specific pH levels is crucial for cell viability.

Applications in the Laboratory and Beyond

One of the most common applications of phenol red is in cell culture. Researchers utilize this compound in growth media for various types of cells, including mammalian cells, to indicate the pH of the environment. The visual changes in color allow scientists to quickly assess whether the culture conditions are optimal, thus facilitating better growth and experimentation outcomes.

In the field of medicine, phenol red is also used as a tracer in diagnostic tests and procedures. It can be found in some formulations used during surgeries to assess the permeability of various tissues and fluids. Its ability to change color under different pH conditions helps medical professionals monitor bodily fluids' acidity levels, which can be vital in diagnosing medical conditions.

Moreover, phenol red has applications beyond the laboratory, including its use in swimwear and other textiles, where it serves as a colorant. However, while its dye properties can be utilized in various industries, it is essential to consider the regulations surrounding its use, particularly in products coming into contact with skin.

Environmental and Safety Considerations

Despite the numerous benefits of phenol red, it is essential to address potential environmental and health implications associated with its use. Phenol and its derivatives can pose risks as they may be harmful when ingested or when they come into contact with skin. Thus, proper handling and adherence to safety guidelines are critical when working with this compound.

Research into the environmental impact of phenol red, especially in wastewater, is ongoing. Efforts are being made to ensure that its use does not adversely affect aquatic life and ecosystems. Effective waste management and disposal strategies should be established to mitigate any negative outcomes.

Conclusion

In summary, phenol red, identified by CAS number 139-07-1, is a significant chemical compound with diverse applications in laboratory settings, medical diagnostics, and even industrial use. Its unique properties allow it to serve as a reliable pH indicator, which is critical for the success of various scientific experiments and medical procedures. As with many chemicals, understanding its properties, benefits, and safety considerations is essential for maximizing its potential while minimizing risks.

Researchers and practitioners continue to explore new ways to utilize phenol red, ensuring it remains an invaluable asset in both scientific research and practical applications. As the fields of biochemistry and biotechnology advance, compounds like phenol red will undoubtedly evolve, paving the way for innovative solutions and discoveries.
