TCI T1110 is 2,3,5,6-Tetrafluoro-1,4-phenylenediamine, CAS number 1198-64-7, an aromatic diamine whose four remaining ring positions are all occupied by fluorine atoms. In the TCI catalogue it is listed under Materials Science, specifically Covalent Organic Frameworks (COFs) Linkers. This means the compound is designed to act as a linker, connecting individual molecular units into ordered, porous frameworks. The two amine groups in the para positions allow it to form imine bonds, as well as other linkages, with aldehyde or anhydride partners, which makes it a practical building block in a materials synthesis laboratory.

Researchers choose this compound for its linear symmetry and the full fluorine substitution of its ring. The two amine groups sit on opposite sides of the ring, giving a geometry well suited to building regular two-dimensional or three-dimensional networks. The fluorine atoms change the electronic character and the intermolecular interactions compared with a non-fluorinated phenylenediamine. This effect is of interest to scientists who want to tune polarity, stability, and surface properties of a material. For the same reason, the compound also attracts attention in the synthesis of fluorinated polymers such as polyimides and polyamides.

In Indonesia, research on porous materials and functional polymers is growing in universities, research institutes, and industrial development laboratories. In these settings, TCI T1110 is typically used by groups that synthesise COFs or fluorinated polymers and need a well-defined diamine linker from an established brand. It is usually handled in small research quantities, in synthesis projects where the choice of building block directly shapes the structure and properties of the final material.

Related TCI products

COF synthesis: the para-positioned diamine can condense with aldehyde partners to form imine-linked frameworks, and its linear geometry supports the construction of regular, ordered porous networks.
Covalent organic framework design studies: the fluorinated ring lets researchers compare frameworks built from fluorinated and non-fluorinated linkers, so the effect of fluorine on structure and behaviour can be examined directly.
Fluorinated polyimide synthesis: the two amine groups can react with anhydrides to form polyimides, and the fluorine substitution on the ring is of interest for tuning the properties of the resulting polymer.
Fluorinated polyamide synthesis: the diamine can be combined with suitable co-monomers to form polyamides, giving polymer chemists a symmetric, fully fluorinated building block with predictable reactivity at both amine sites.
Surface and polarity tuning research: the fluorine atoms alter electronic character and intermolecular interactions, which suits studies aimed at adjusting the polarity, stability, and surface properties of functional materials.

Product code: T1110

Store 2,3,5,6-Tetrafluoro-1,4-phenylenediamine in its original, tightly closed container, in a cool, dry, well-ventilated place away from direct light, heat, and incompatible materials. Always follow the storage instructions on the supplier's label and safety data sheet, since these take precedence over general guidance. Keep the bottle closed when not in use to limit exposure to moisture and air. As with any aromatic amine, handle it in a fume hood or a well-ventilated area and wear a laboratory coat, chemical-resistant gloves, and safety glasses. Avoid generating dust, avoid skin and eye contact, and wash hands after handling. Dispose of waste according to your institution's chemical waste procedures.
