What is 6FDA used for?

6FDA may be evaluated as a monomer in polyimide and other polymer-synthesis work. The intended polymer system, stoichiometry, solvent and reaction conditions should be specified because this fluorinated aromatic dianhydride is a synthesis input, not a finished polymer.

Which specifications should be agreed for Polyimide-grade 6FDA?

Agree HPLC assay, appearance and colour, water, anhydride or hydrolyzed-acid control, residual solvent, insoluble matter and individual metal-ion limits with the test methods. Commercial high-purity grades may quote high assay and very low metals, but the full specification must be confirmed.

What packaging and storage details should be confirmed for 6FDA supply?

Confirm moisture-barrier inner packaging, seal integrity, net weight, manufacturing date, quoted shelf-life basis and cool, dry storage conditions. The dianhydride can convert toward the corresponding acid after moisture exposure, so agree resealing and storage controls.

Which polymer-synthesis parameters should be specified for 6FDA?

Specify the intended polyimide system, diamine or co-monomer stoichiometry, solvent, imidization route and target molecular weight or viscosity. Also state required monomer purity, water limits and moisture-control needs, because 6FDA is moisture-sensitive and can hydrolyze toward the corresponding acid.

Hexafluoroisopropylidene Diphthalic Anhydride (6FDA) CAS 1107-00-2

6FDA, CAS 1107-00-2, is 4,4'(hexafluoroisopropylidene)diphthalic anhydride. It is a fluorinated aromatic dianhydride monomer used in polyimide and related polymer synthesis. Confirm the target polymer system, purity or impurity controls, quantity, packaging and document requirements before requesting specifications and quotation.

Technical context

Chemical identity

6FDA is the established abbreviation for 4,4′-(Hexafluoroisopropylidene)diphthalic anhydride, CAS 1107-00-2.
It is a fluorinated aromatic dianhydride, not a finished polymer.

Polymer synthesis context

6FDA may be evaluated as a monomer in polyimide and other polymer-synthesis work.
The intended polymer system, impurity limits, and moisture controls should be reviewed against the current specification of the material proposed.

Application boundary

This page does not establish electronic grade, display, semiconductor, membrane, or optical-film suitability for the offered material.

Specification and documentation

This page does not confirm a supplier specification, package, certificate, or document availability.

Request a current product specification that matches the intended use.
Confirm whether any requested document is available for the offered material.
Confirm packaging after the product form and destination requirements are known.

Storage and safety

Handling and storage

This page is not a storage or handling instruction.
Review the current SDS for the exact material proposed before handling, storage, or transport decisions.
The receiving site should set controls for its own process and local requirements.

Safety review

Confirm hazard classification and transport classification from current product documentation.
Determine PPE and emergency measures from the current SDS and site assessment.
Confirm compatibility with the intended process before use.

FAQ - Technical & Supply Chain

Q:
Are 6FDA and Hexafluoroisopropylidene Diphthalic Anhydride the same monomer?

A: Yes. 6FDA is the established abbreviation for 4,4'-(hexafluoroisopropylidene)diphthalic anhydride, CAS 1107-00-2, a fluorinated dianhydride monomer used in polyimide production. It is not a finished polyimide or another phthalic anhydride isomer. State the CAS number and monomer identity.
