Solubility: soluble in water, ethanol, ether, soluble in chloroform, carbon tetrachloride, insoluble in benzene.

Chemical properties: resorcinol is similar to dibasic acid in chemical properties, and reacts with sodium hydroxide and ammonia water to form salt. Resorcinol can react with acetic anhydride to form ester. Under the catalysis of zinc chloride, phenylene diphenolphthalein can be formed by condensation reaction with phthalic anhydride, and luciferin can be formed by further dehydration.

Flammability: combustible.

Used in dye industry, plastic industry, medicine, rubber and so on. Resorcinol is mainly used for rubber adhesives, synthetic resins, dyes, preservatives, medicine and analytical reagent, such as primary side, resorcinol and phenol, cresol are similar, and formaldehyde condensation polymer, can be used in making viscose rayon and nylon tyre cord adhesive, preparation of cement, wood glue used for vinyl material and metal, resorcinol is many azo dye, fur dyes intermediates, raw materials and pharmaceutical intermediates for nitrogen base salicylic acid. Resorcinol has bactericidal effect, can be used as antiseptic, in cosmetics and skin diseases medicine paste and ointment. The derivative of resorcin, betamethyl atropine, is the intermediate of optical bleach, trinitro-resorcin is the detonator of detonator, and a considerable amount of resorcin is used in the production of ultraviolet absorbent of resorcin. This product can irritate the skin and mucous membrane, can quickly absorb through the skin and cause poisoning symptoms.
