Application:

1 resorcinol, also known as 1, 3-resorcinol, commonly known as resorcinol. The intermediate 3-chloro-4-methyl coumarin and herbicide ethoxyflufen are used in the synthesis of insecticide phosphor on pesticides, and can also be used in the manufacture of a variety of dyes, special coatings, medicine, photosensitive materials, synthetic resins, adhesives, cosmetics and so on.

2 Used in photographic film, medicine, dyes and chemical fiber industry

3 Used as an analytical reagent

4 Resorcinol is mainly used in rubber adhesives, synthetic resins, dyes, preservatives, medicine and analytical reagents, etc. Resorcinol is similar to phenol and cresol, and forms condensation polymers with formaldehyde, which can be used to make viscose silk and nylon tire cord binder, prepare wood adhesive, and be used to bond vinyl materials with metals. Resorcinol is the intermediate of many azo dyes and fur dyes, and also the raw material of p-nitrosalicylic acid in pharmaceutical intermediates. Resorcinol has a bactericidal effect, can be used as a preservative, added to cosmetics and dermatological drug paste and ointment. A derivative of resorcinol, beta-methylumbellione, is an intermediate in optical bleach, trinitroresorcinol is a detonator, and considerable quantities of resorcinol are used in the production of benzophenone UV absorbers. This product can stimulate the skin and mucous membrane, can be absorbed quickly through the skin to cause toxicosis. The lowest lethal dose of subcutaneous injection in rats is 450mg/kg.

5 Determination and colorimetric determination of zinc, lead, tartaric acid, nitrate and nitrite, colorimetric determination of furfuryl alcohol and sugar, reagent for testing ketose and lignin, reagent for diazo compounds salt, organic synthesis.

Matters needing attention

1, can make light hair black, a few days after the drug can make the skin redness and desquamation, should be used with caution.

2. Patients with dark skin can stimulate pigment production.

3. Used with soaps, cleansers, acne preparations, alcohol-containing preparations or retinoic acid, which can cause excessive skin irritation or dryness.
