1,5-Hexadiene-3,4-diol (CAS 1069-23-4) from TCI is an unsaturated diol that carries two adjacent hydroxyl groups at the 3 and 4 positions together with two vinyl groups at either end of the carbon chain. The product is supplied in a form stabilized with hydroquinone (HQ) to prevent spontaneous polymerization during storage. Within the polymer reagent category, this compound serves as both a monomer and a versatile intermediate: its diene backbone opens routes to polymerization and addition reactions, while its diol pair provides attachment points for further modification. The 10 mL pack suits laboratory-scale synthesis and formulation work.
The characteristic that makes this material a preferred choice is the presence of four reactive centers within a single small molecule: two terminal double bonds and two vicinal hydroxyl groups. The terminal double bonds are readily engaged in metathesis, hydroformylation, epoxidation, and radical polymerization, while the vicinal diol can be protected as an acetonide, converted into esters or ethers, or used as a stereochemistry-directing group. The compound also possesses multiple stereogenic centers, which makes it of interest for asymmetric synthesis studies. The presence of the hydroquinone stabilizer keeps the material usable across a normal working period without premature crosslinking.
In Indonesian laboratories, this reagent is typically encountered in university and institutional research groups working on polymer chemistry, organic synthesis methodology, and materials development. The 10 mL format matches the scale at which such groups run exploratory reactions, screen conditions, and prepare small batches of modified monomers. It is generally ordered as a specialty item for a defined project rather than held as a bulk consumable, and is handled alongside other air- and heat-sensitive reagents in the same fume hood workflow.
- Monomer for polymerization studies: the two terminal vinyl groups allow the molecule to be incorporated as a difunctional monomer or crosslinker in radical polymerization experiments where network formation is being investigated.
- Olefin metathesis substrate: the pair of terminal double bonds makes this diol a convenient starting point for ring-closing or cross-metathesis routes toward cyclic and functionalized unsaturated frameworks in methodology work.
- Building block for diol-functionalized intermediates: the vicinal hydroxyl pair can be esterified, etherified, or protected as an acetonide, giving synthetic chemists a flexible handle for multi-step sequences.
- Asymmetric synthesis investigations: because the molecule contains multiple stereogenic centers alongside its reactive alkenes, it is useful for studying stereocontrol and chiral induction in laboratory-scale transformations.
- Epoxidation and hydroformylation chemistry: the unhindered terminal alkenes respond well to oxidation and carbonylation conditions, making this compound a practical test substrate when developing or benchmarking such reactions.

Keep the container tightly closed in its original packaging and store it in a cool, dark place away from heat sources, direct sunlight, and ignition sources, since polymerizable monomers are sensitive to warmth and light. Do not remove or dilute the hydroquinone stabilizer, and avoid prolonged storage of decanted portions. Handle the material in a fume hood using nitrile gloves, safety glasses, and a laboratory coat, and transfer it with clean glass or otherwise compatible equipment. Keep it separated from strong oxidizing agents, acids, and radical initiators, and follow your institution's waste procedures for organic residues.
