This page looks at the structure and physical properties of phenol (very old name: carbolic acid). … Phenol is the simplest member of a family of compounds in which an -OH group is attached directly to a benzene ring. The ‘Hazard classification and labelling’ section shows the hazards of a substance based on the standardised system of statements and pictograms established under the CLP (Classification Labelling and Packaging) Regulation. In the preceding section you saw that the red form of phenol red gave a narrower and higher max than did the yellow form. The lambda max of the red form was approximately 550 nm while the yellow form had a minimum at 550 nm. Hazard classification & labelling Hazard classification and labelling. Phenol red has been used in the PSP test for kidney functions; Most recently, medical researchers have discovered that phenol red can serve as an estrogen mimic and is used in the process of in vitro fertilization; Phenol red is a dye used in automotive coolants; Allow Abbey Color to color your world. Phenol red binds to the estrogen receptor of MCF-7 human breast cancer cells with an affinity 0.001% that of estradiol (Kd = 2 X 10(-5) M). Contact Us . ... Phenol Red sodium salt.

That means that a very dilute solution isn't really acidic enough to turn litmus paper fully red. Properties of phenol as an acid. This means that assaying phenol red in the red form will give a more sensitive assay than if you attempted to essay it in the yellow form. The structure of phenol. With indicators. Phenol itself is the only one of the family that you are likely to need to know about for UK A level purposes. The pH of a typical dilute solution of phenol in water is likely to be around 5 - 6 (depending on its concentration). It stimulates the proliferation of estrogen receptor-positive MCF-7 breast cancer cells in a dose-dependent manner but has no effect on the growth of estrogen receptor-negative MDA-MB-231 breast cancer cells.
