Methyl orange 0,1 %, aqueous

Methyl Orange 0.1%, aqueous is a single solution used in medical diagnostics, histology and scientific laboratories. It is an aqueous solution of methyl orange (C.I.: 13025) (CAS No.: 547-58-0). Methyl orange (C14H14N3NaO3S) is an azo dye and a pH indicator that changes color when the pH changes between acidic and basic. Aqua dest. / DI water (also known as deionized water or demineralized water) is a type of ultrapure water processed by removing ions.

In histology and medical diagnostics, methyl orange is used to distinguish acidic tissue components or structures (such as intracellular vacuoles) from basic ones. It is also used in microscopic examination of biological specimens. In scientific laboratories, methyl orange serves as a pH indicator and helps determine pH levels in various solutions. It is also used in titration experiments where the end point of a chemical reaction is indicated by a visible color change.

The chemical reaction between methyl orange and acids or bases results in a color change. In acidic environments (pH <3.1), methyl orange is red, while in basic environments (pH >4.4) it is yellow. In a transition range from pH 3.1 to 4.4, methyl orange exhibits an orange color. The color changes are due to structural changes in the molecule caused by protonation and deprotonation of the azo dye groups in the molecule.

As an indicator of acidic and basic structures, methyl orange 0.1%, aqueous is an essential solution in the field of medical diagnostics and histology.
