2,4,6-Tribromophenol CAS 118-79-6

2,4,6-Tribromophenol is a multi-purpose bromine-based flame retardant. It can not only serve as a reactive flame retardant for resins such as epoxy resin and polyurethane, but also as an intermediate for new high-performance flame retardants like brominated polyphenyl ethers, phosphite esters, and phosphate esters. Additionally, it can function as a preservative for wood, paper, and other materials, and as a component of composite flame retardants used in other resins, demonstrating a very wide range of applications.

product superiority

1.Ultra-high bromine loading (72.5 %) delivers more fire-suppressing efficiency per part than most aryl flame-retardant additives, allowing lower dosage and minimal impact on polymer mechanicals.

2.Excellent thermal stability: begins to decompose above 230 °C, providing a wide processing window for thermoplastics such as PET, PBT, ABS and HIPS.

3.Low smoke & low acid-gas emission during combustion; LOI values > 30 and UL-94 V-0 ratings are routinely achieved at 8–12 phr, meeting stringent FRLS cable and electronics standards.

4.Dual-function molecule: acts both as an active flame-retardant and as a brominating agent in fine-chemical synthesis, reducing the need for elemental bromine or hazardous reagents.

5.Readily soluble in common industrial solvents (ethers, ketones, aqueous alkali) yet only 0.2 g L⁻¹ in water, facilitating easy recovery and low aquatic-leaching risk.

6.Stable crystalline solid (m.p. 92–95 °C) with low hygroscopicity; non-volatile under ambient conditions, simplifying storage and handling compared with liquid bromine derivatives.

7.High chemical purity (≥ 99 % HPLC) and low ionic residue (< 10 ppm heavy metals) make it suitable for electronic, pharmaceutical and photographic-grade applications.

8.Favorable toxicological profile—non-carcinogenic, non-mutagenic, not listed in major hazardous chemical inventories, allowing simpler regulatory compliance and transport.

9.Compatible with existing epoxy, polyurethane and polyester curing chemistries; improves melt flow and impact strength when used as a reactive end-capper.

10.Supplied in 25 kg HDPE drums with multi-layer liners; two-year shelf-life under cool, dry conditions—minimizing inventory losses and ensuring consistent batch-to-batch performance

application

1. Reactive flame-retardant for epoxy, PU, polyester resins (UL-94 V-0)

2. Additive FR in ABS, HIPS, PET, PBT, wire & cable (LOI ≥ 30)

3. Intermediate for TBBPA, brominated oligomers, fine chemicals

4. Biocide in wood, coatings, metal-working fluids

5. Oilfield drilling-mud biocide; pharmaceutical & agro building block

6. Electronic-grade dopant and analytical standard
