Resorcinol is a colouring agent for some chromatography experiments.
a
It help to separate and analyze colorless substances in chromatography by reacting with the colorless substance to form colored spots on the chromatogram.
Resorcinol
Towards the centre of the chromatogram. The smaller molecules are more mobile and appear towards the outside of the chromatogram.

Two ways of identifying amino acids on a chromatogram are paper and gas.

Resorcinol is used to test honey to see if sugar has been added to the honey. After adding the solution of resorcinol to the honey boil it, if the mixture turns red it means sugar is added and the honey is not pure.
During the development of a chromatogram, it is better to cover it with a beaker to prevent evaporation, which will affect the movement of the solute and solvent system. This will ensure that the chromatogram will develop properly.

Resorcinol is used as the complexing agent to provide the color reaction, although the exact nature of the colored product is not known. Since resorcinol favors electrophilic aromatic substitution, the reaction may be similar to the Molisch Test.

Resorcinol is 1,3-dihydroxy benzene, it is acidic and two 'OH' groups make the system sufficiently polar so it is soluble in polar solvent water.
