Phenol, 4,4'-(1,1-dioxido-3H-2,1-benzoxathiol-3-ylidene)bis-

Description:

Phenol, 4,4'-(1,1-dioxido-3H-2,1-benzoxathiol-3-ylidene)bis-, also known by its CAS number 143-74-8, is a chemical compound characterized by its phenolic structure combined with a benzoxathiol moiety. This compound typically exhibits properties associated with both phenols and heterocyclic compounds, including potential antioxidant and antimicrobial activities. The presence of the dioxido group suggests that it may have enhanced reactivity or stability under certain conditions. It is generally soluble in organic solvents and may have limited solubility in water, which is common for many phenolic compounds. The compound's structure allows for various applications in organic synthesis, materials science, and potentially in pharmaceuticals, given the biological activity often associated with phenolic derivatives. Safety data should be consulted for handling and exposure risks, as phenolic compounds can be toxic and irritative. Overall, this compound represents a unique intersection of organic chemistry and potential applications in various fields.

Phenol red

CAS: 143-74-8

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.
