Description
TCI D3587 1,8-Dibromohexadecafluorooctane is a perfluoroalkyl compound built on an eight-carbon chain that carries a bromine atom at each end, while every remaining carbon position is saturated with fluorine atoms. This bifunctional architecture is what makes it a high-value fluorinated building block in synthetic chemistry laboratories. The carbon–bromine bonds at both ends of the chain are far more reactive than the very strong carbon–fluorine bonds, so the compound can act as a source of perfluoroalkyl radicals or as a bidirectional linker for inserting a perfluoroalkylene segment into target molecules, polymers, or surface materials.
The property that makes this reagent dependable is the combination of chemical inertness along the perfluorinated chain and controlled reactivity at its bromine groups. The perfluoroalkyl chain delivers very low surface energy, behaviour that is both hydrophobic and oleophobic, high thermal stability, and a strong affinity for the fluorous phase, which is why derivatives prepared from it are frequently used in fluorous biphasic chemistry. The two terminal bromine atoms open the door to radical substitution reactions, metal-catalysed coupling, or the formation of organometallic reagents, allowing researchers to construct structures around a rigid, well-defined fluorinated core.
In Indonesian laboratories, this type of fluorinated building block is typically handled in university and institutional research groups working on synthetic organic chemistry, fluoropolymers, surface modification, and advanced materials. It is normally requested in research quantities rather than production volumes, kept in the fine-chemical section of the reagent store, and dispensed inside a fume hood for small-scale reaction work. Because the compound is used as an intermediate, laboratories usually plan their consumption around specific project stages and keep the container closed between uses.
Laboratory Applications
- Perfluoroalkyl radical generation — the weak carbon–bromine bonds at both chain ends release perfluoroalkyl radicals under suitable initiation, giving a controlled entry point into radical fluoroalkylation chemistry.
- Bidirectional linker synthesis — because both termini are reactive, the compound inserts a complete perfluoroalkylene segment between two molecular fragments in a single, structurally defined bridging step.
- Fluorous biphasic chemistry — derivatives built from this perfluorinated chain show strong affinity for the fluorous phase, supporting phase-separation strategies for catalyst recovery and product purification workflows.
- Surface and material modification — the very low surface energy of the perfluoroalkyl chain lets researchers graft hydrophobic and oleophobic character onto polymers, coatings, and prepared surface materials.
- Organometallic reagent preparation — the terminal bromines can be converted into organometallic species or used in metal-catalysed coupling, extending the fluorinated core into more elaborate target structures.

Handling and Storage
Store the reagent in its original tightly closed container in a cool, dry, well-ventilated chemical store, away from heat sources, direct sunlight, and incompatible materials. Keep it in the manufacturer-supplied glass or fluoropolymer-compatible packaging rather than transferring it to unverified plastic containers. All dispensing and reaction setup should be carried out inside a working fume hood, using nitrile gloves, safety goggles, and a laboratory coat. Avoid inhalation of vapours and contact with skin or eyes, return the container to storage promptly after use, and collect halogenated waste separately according to your institution's chemical waste procedures. Always consult the manufacturer's safety data sheet before first use.
