Bromophenol Blue Lab Report

Description:
IC50: N/A

Bromophenol blue (3',3",5',5"-tetrabromophenolsulfonphthalein) is widely used in gel loading buffers. Bromophenol blue is used as a pH indicator, a color marker, and a dye. Bromophenol blue can be prepared by slowly adding excess bromine to a hot solution of phenolsulfonphthalein in glacial acetic acid.

In vitro: Previous results showed that the adsorption process of bromophenol blue increased with increase in the concentration of α-chitin nanoparticles (CNP), contact time and temperature, while the adsorption process decreased with increase in the initial dye concentration and strong acidic pH. The Fourier transform infrared spectroscopy results confirmed that the interaction between Bromophenol blue and CNP

    Mechanism 4 shows the debromination of 2α-bromocholestan-3-one to give 4. This mechanism which is similar to a Favoskii rearrangement, is likely to go via this path as other research has shown that there is often a by-product with this reaction. The by-product is cholest-4-en-3-one which requires the intermediate seen in the third molecule in the above mechanism. The intermediate is highly strained and with the presence of base a proton will be extracted which aids the collapse of the three membered ring. To gain the major product, 4, the H1 proton is removed, however it is very possible that the H4 proton is removed instead which would leave the minor product of cholest-4-en-3-one. Both products result in conjugation which will stabilise the molecule. The mechanism for this step is unlikely to go via a simple elimination as for an elimination the eliminated products must be trans to each other for facile leaving. As the bromine is equatorial in both the chair and the boat conformation the bromine is trans with neither of the hydrogens which shows this type of elimination is unlikely to occur. The other possibility is that the acidic hydrogen that is removed in the first step is not H4, but H2. This…

    The final compound which I am going to look at is 4-aminobenzenecarboxylic acid. The compound is also known as 4-Aminobenzoic acid. The molecular and structural formula of the compound is C7H7NO2 which means that the compound consists of seven carbon atoms attached to seven hydrogen atoms along with one nitrogen atom and two carbon atoms attached as a carbon-oxygen double bond. The displayed formula for the 4-aminobenzenecarboxylic acid compound is shown and it shows the formula in a ring form therefore means that the compound is an aromatic compound. This is an aromatic compound because the compound consists of six carbons of benzene joined in a ring, having the planar geometry of a regular hexagon in which the distance between all of the C-C bonds are equal.…

    Bromothymol blue indicator changes color depending on the pH of a solution. The indicator would change from blue to green to yellow. Using this indicator, we were able to measure the rate of formation of HCl by measuring the time in which the indicator turned blue to green and the amount of NaOH needed to turn it from green to blue again. The time and volume would then be used to obtain the rate constants. Bromothymol blue is a weak acid so it can be protonated and deprotonated causing it to appear yellow and blue.…
