Resorcinol (1,3-Benzenediol, m-Dihydroxybenzene)

CAS 108-46-3 · Formula C6H6O2 · MW 110.11 g/mol

A reactive dihydroxybenzene building block for rubber-bonding resins, adhesives, and dye intermediates. Its primary industrial use is as a monomer for resorcinol-formaldehyde resins and adhesives used in tire-cord and rubber-to-textile bonding and in high-performance wood adhesives; it also serves as an intermediate for dyes and UV light stabilizers and as a reagent in tanning and textile processing.

Full Description

Resorcinol (CAS 108-46-3; C6H6O2), the meta isomer of dihydroxybenzene, supplied as a crystalline powder. Its primary industrial use is as a monomer for resorcinol-formaldehyde resins and adhesives used in tire-cord and rubber-to-textile bonding and in high-performance wood adhesives; it also serves as an intermediate for dyes and UV light stabilizers and as a reagent in tanning and textile processing.

Frequently Asked Questions

What is the use of resorcinol powder?

Resorcinol (CAS 108-46-3) is used primarily as a monomer for resorcinol-formaldehyde resins and adhesives in tire-cord and rubber-to-textile bonding and in high-performance wood adhesives. It also serves as an intermediate for dyes and UV light stabilizers and as a reagent in tanning and textile processing.

What is resorcinol made from and what is its structure?

Resorcinol is the meta isomer of dihydroxybenzene (C6H6O2), with two hydroxyl groups in the 1,3 positions on a benzene ring. It is supplied as a crystalline powder to USP specification under CAS 108-46-3.

Is resorcinol the same as retinol?

No. Resorcinol is a dihydroxybenzene (C6H6O2) used mainly in resins, adhesives, dyes, and tanning. Retinol is vitamin A in its alcohol form (C20H30O), a separate compound; the names are unrelated despite sounding similar.

What UN number applies when shipping resorcinol?

Resorcinol ships under UN 2876 (RESORCINOL). Provide this UN number to your carrier and freight forwarder, and refer to the SDS for the proper shipping name, packing group, and any mode-specific requirements before dispatch.

What is the cost of bulk resorcinol USP powder and what packaging is available?

Pricing depends on volume and market conditions, so RawSource quotes per order. Submit a bulk RFQ with your required quantity to receive pack sizes, MOQ, lead time, and a CoA/SDS; reference HS heading 2907.21 for import classification.
