Resorcinol is a dihydroxybenzene compound widely recognized in chemical processing as resorcin, m‑dihydroxybenzene, or 1,3‑benzenediol within the same material identity. Identified by CAS 108-46-3, it contains two hydroxyl groups positioned on the aromatic ring, enabling controlled condensation and crosslinking behavior, which makes it suitable for industrial reaction systems requiring phenolic functionality. It is typically applied in resin synthesis, where it participates in formaldehyde-based condensation processes and related intermediate manufacturing under defined process conditions.
For industrial supply, this product is available with competitive factory pricing, supports customized specifications, and is provided with MSDS, TDS, COA documentation, with capacity for bulk supply.

FAQ - Technical & Supply Chain
-
Q:
Is Resorcinol with CAS 108-46-3 chemically identical to 1,3-dihydroxybenzene used in industrial formulations?
A: Yes. CAS 108-46-3 corresponds to Resorcinol, which is the standardized industrial and regulatory identifier for 1,3-dihydroxybenzene within chemical manufacturing and formulation systems. -
Q:
Is Resorcinol typically applied directly in resin synthesis processes or only as a laboratory reagent?
A: Resorcinol is commonly used as a raw material in industrial resin synthesis processes, particularly in phenolic and formaldehyde-based reaction systems, rather than being limited to laboratory-scale research use.
