Dilute water solutions of resorcin (dihydroxybenzene) are used as antiseptic, disinfectants and as components in drugs for dermathology treatments.
Resorcinol resin glues are a high strength wood glue much used in vintage aircraft. Nowadays modern epoxies are taking it's place.
The formula is C6H6O2 and it is 1,3-dihydroxy benzene.
4-(4-nitrophenylazo)resorcinol
Zinc chloride and an acid must be present, preferably HCl
Seliwanoff's test is used to differentiate aldose [glucose] from ketose [fructose]. Seliwanoff's reagent is composed of resorcinol and HCl. When heated with concentrated hydrochloric acid, the polysaccharides and oligosaccharides hydrolyze to yield monosaccharides. Then, resorcinol reacts in the dehydrated ketose to form oxymethylfurfurol produce a deep cherry red color [red precipitate]. Aldoses produces a faint pink colored solution.
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.
Resorcinol is a colouring agent for some chromatography experiments.
Resorcinol
1,3-dihydroxybenzene
catechol
meta Dihydroxybenzene
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.

I believe so.
