What Is Tetrabromophthalic Anhydride (TBPA)?
Tetrabromophthalic anhydride is a brominated aromatic anhydride used as a reactive intermediate in selected flame-retardant resin systems. Its anhydride functionality distinguishes it from brominated additive powders that are blended without reaction. The correct molecular formula for CAS 632-79-1 is C8Br4O3.
The TDS specifies bromine ≥67.0%, melting point ≥270°C, sulfate ≤0.15%, moisture ≤0.20% and neutralization equivalent 228–242 g/eq. Retain the test basis and units when comparing incoming material or designing a reaction stoichiometry.
Unsaturated polyester, polyurethane-intermediate and epoxy-related development requires assessment of reaction completion, viscosity, cure response, colour and the final polymer properties. Bromine content alone cannot establish the fire-test outcome of a finished resin or article.
TBPA also serves as an intermediate for brominated ester and imide synthesis. Protect the anhydride from moisture and control powder exposure during charging. The solid transport reference is non-dangerous goods, while skin sensitization and irritation still require chemical hazard labelling and appropriate handling controls.

Tetrabromophthalic Anhydride (TBPA) Applications
Reactive resin intermediates
Brominated anhydride for selected unsaturated polyester and polyurethane-intermediate development. Assess reaction stoichiometry, conversion, viscosity and cured performance.
Brominated ester and imide synthesis
Intermediate for selected downstream brominated compounds. Match purity and moisture control to the reaction and purification requirements.
Epoxy-related formulation development
Reactive intermediate for selected resin systems. Evaluate cure response, compatibility and finished-system fire performance before fixing a loading.
