DESCRIPTION

Resorcinol is a white to slightly pink crystalline solid with a faint phenolic odor.
Resorcinol darkens upon exposure to light or air due to slow oxidation.
Resorcinol is soluble in water, alcohol, acetone, and ether, and slightly soluble in chloroform.

Resorcinol is a meta-dihydroxybenzene isomer, featuring two hydroxyl groups attached to the benzene ring in the 1,3-positions.
This configuration provides high reactivity toward electrophilic and condensation reactions.
Resorcinol readily forms condensation products with formaldehyde and amines.

Resorcinol exhibits strong antiseptic, antifungal, and keratolytic properties.

It acts as a mild disinfectant and fungicide in topical formulations.

Resorcinol is chemically stable under normal storage conditions but oxidizes slowly in air.
Resorcinol is reactive with strong oxidizing agents and concentrated acids.
Resorcinol should be stored in airtight containers away from light and heat.

Resorcinol is non-volatile and moderately hygroscopic.
Resorcinol melts to a clear liquid and sublimes at higher temperatures.
It can be handled safely using standard laboratory precautions.
