Density, melting range and boiling point are literature values. Formula and molecular weight refer to TBC itself, not the solution grade.
Commercial Information
Storage & Shipping
Storage Conditions
Keep tightly closed in a cool, dry, ventilated corrosives area. Protect solid TBC from moisture and unnecessary air exposure. Keep solution grades away from heat and ignition; separate from oxidizers, alkalis and incompatible metals.
Packaging Integrity
Inspect solid-grade drum liners and solution IBC closures before use. Keep each grade and solvent clearly identified, avoid cross-contamination and preserve package seals during storage and transport.
Packaging
99% solid: 25 kg drums / 85% solution: 1,100 kg IBC
Handling & Protection
Use controlled dispensing and effective ventilation. Avoid solid dust, solution mist and splashes. Wear chemical-resistant gloves, protective clothing, splash goggles and face protection. Apply solvent-specific ignition controls for methanol-containing grades.
What Is 4-tert-Butylcatechol (TBC)?
4-tert-Butylcatechol (TBC), CAS 98-29-3, C10H14O2, molecular weight 166.22 g/mol, is a polymerization inhibitor. It is the standard inhibitor added to styrene, butadiene and other reactive monomers during storage and transport, where it works together with dissolved oxygen.
Two forms are available: solid flakes with purity above 99%, and an 85% solution in water or methanol. The solvent is confirmed on order, because the two solutions have different safety requirements and are not interchangeable.
Solid TBC ships as UN 3261, Class 8, packing group II; the aqueous solution as UN 3265. A methanol solution has additional flammability hazards and its own SDS.
As a TBC supplier and exporter in China, ZXCHEM packs the 99% flakes in 25 kg drums and the 85% solution in 1,100 kg IBCs.
