Methyl red hydrochloride

Methyl red hydrochloride is a pH-sensitive acid-base indicator and colorimetric reagent with a pKa of 5.1. Methyl red hydrochloride achieves visual judgment of the titration endpoint through reversible structural changes of protonation (red, pH < 4.4) and deprotonation (yellow, pH > 6.2). Methyl red hydrochloride is widely used in acid-base titration in chemical analysis and buffer pH monitoring in biochemistry.

Biological Activity

제품 설명

In Vitro

Methyl red hydrochloride is used as an acid-base indicator in titration experiments. When the pH changes from 4.4 to 6.2, the color of the solution changes from red to yellow, which can be used to determine the titration endpoint^[1].
Methyl red hydrochloride can be dissolved in ethanol to make a 0.1% solution. A few drops are added to the solution to be tested. During the titration process, the color change is observed to determine the pH endpoint^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
