Source-derived summary

3,3’,4,4’-Benzophenone tetracarboxylic dianhydride (BTDA) is, chemically, an aromatic organic acid dianhydride.

Uses

Its use in epoxy powder coatings is slightly unusual in that many epoxy coatings are designed to be fairly close to a stoichiometric curing ratio. BTDA cured materials benefit from having the stoichiometry closer to 0.65 rather than 1. It is also used to synthesize polyimides. These have good flexibility because of the carbonyl and keto groups which increase the molecular distancing between the imide rings. This improves the solubility. The resultant product when combined with nano-technology produces composites with enhanced heat stability properties.

Safety

It is REACH and TSCA registered. Exposure causes serious eye irritation and may cause respiratory irritation.

Trademark

The name BTDA is a registered trademark of company Jayhawk Fine Chemicals Corporation.

Editorial summary

The public source identifies “3,3',4,4'-Benzophenone tetracarboxylic dianhydride” as chemical compound. This brief keeps that definition visible, then builds a research path around 4'-Benzophenone, tetracarboxylic and dianhydride.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current 127-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with 4'-Benzophenone, tetracarboxylic and dianhydride providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “3,3',4,4'-Benzophenone tetracarboxylic dianhydride”, the useful work is to connect “chemical compound” to the records capable of establishing context and consequence.

Evidence profile

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Sep 24, 2026. The linked authority identifier is Q27294296. None of the 0 selected statements returned an explicit reference.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
