Description
TCI D3411 Di-tert-butyl Peroxide (CAS 110-05-4) is a symmetrical dialkyl peroxide that has long served as one of the most dependable radical initiators in organic synthesis laboratories. Its molecule consists of two tert-butyl groups joined by a single oxygen–oxygen bond. When the compound is heated or exposed to ultraviolet light, that weak bond cleaves homolytically and releases two highly reactive tert-butoxy radicals. These radicals are what start the chain sequences behind polymerization, radical addition reactions, and a wide range of oxidative transformations carried out in the reaction flask.
The property that most often leads chemists to select this reagent is its comparatively high thermal stability relative to many other peroxides. Because decomposition only begins at a reasonably elevated temperature, the material can be stored and handled at room temperature with sensible caution, while still delivering a steady and controllable supply of radicals once the reaction is run hot. The tert-butoxy radicals it generates are highly effective at hydrogen atom abstraction, a characteristic exploited in C–H bond functionalization. The compound also dissolves readily in non-polar organic solvents and leaves behind no acidic residue, so it rarely interferes with the substrate.
In Indonesian laboratories, this profile suits synthetic chemistry groups in universities, research institutes, and industrial R&D units that need a reliable thermal initiator for method development and scale-up trials. Room-temperature handling with reasonable precautions is a practical advantage where cold-chain capacity is limited, and the absence of acidic residues simplifies workup for teams processing sensitive substrates across teaching, research, and quality-focused synthetic work.
Laboratory Applications
Radical polymerization initiation — the peroxide decomposes thermally to two tert-butoxy radicals that begin and sustain chain growth under controlled hot-reaction conditions.
C–H bond functionalization — the tert-butoxy radicals generated are highly effective hydrogen atom abstractors, which is precisely the property this class of transformation depends upon.
Radical addition reactions — a steady, controllable radical supply at elevated temperature lets chemists drive addition chemistry without an unpredictable early burst of initiator decomposition.
Oxidative transformations — the oxygen–oxygen bond provides the radical source needed for a broad range of oxidative conversions performed in the reaction flask.
Non-polar solvent systems — the compound dissolves well in non-polar organic solvents and leaves no acidic residue, so it seldom interferes with delicate reaction substrates.
Pack Sizes: available in standard TCI catalogue pack sizes — please confirm the required quantity when ordering
Storage: may be stored and handled at room temperature with reasonable caution, given its relatively high thermal stability among peroxides
Handling and Storage
Store the reagent in its original tightly closed container, kept away from heat sources, open flames, direct sunlight, and ultraviolet light, since both heat and UV exposure trigger homolytic cleavage of the oxygen–oxygen bond. A cool, dry, well-ventilated storage area separated from incompatible materials is appropriate. Keep the compound away from ignition sources and handle it in a fume hood using standard laboratory personal protective equipment, including safety glasses, gloves, and a laboratory coat. Dispense only the quantity needed for the reaction, avoid contamination of the bulk container, and consult the manufacturer's safety data sheet before use.
