Description
TCI D2691 5-Dodecene is a non-heterocyclic building block classified as an internal olefin, built on a twelve-carbon chain carrying a double bond at the fifth position. In organic synthesis laboratories, long-chain internal alkenes of this type serve as starting materials for converting a carbon-carbon double bond into a wide range of functional groups, including epoxides, diols, aldehydes, and other addition products. The compound is also frequently employed as a model substrate in catalyst testing, because the reactivity of an internal alkene differs markedly from that of a terminal alkene and therefore provides a more demanding picture of how a catalytic system actually performs.
The property that makes this material a preferred choice is the combination of a long, strongly hydrophobic hydrocarbon chain with a single reactive site in the form of one double bond. Because no other competing functional groups are present, reaction outcomes are easier to interpret and reaction progress can be followed clearly by gas chromatography or NMR. The internal placement of the double bond additionally makes the compound useful for studying positional isomerization as well as cis-trans selectivity. Its good solubility in non-polar solvents such as hexane and dichloromethane supports a broad range of reaction conditions.
In Indonesian laboratories, this building block is typically used in university and institutional research groups working on organic synthesis and catalysis, as well as in industrial R&D laboratories that develop and screen catalytic systems. It is commonly handled at bench scale for functional group transformation studies, method development, and reference work where a clean, single-site olefin substrate is required and where results must be tracked reliably by chromatographic or spectroscopic analysis.
Laboratory Applications
- Epoxidation studies: the isolated internal double bond gives a single, well-defined reaction site, so epoxide formation can be followed and interpreted without interference from competing functional groups.
- Dihydroxylation and diol synthesis: the compound converts cleanly into long-chain diols, making it a practical substrate for teaching and optimizing addition chemistry across a carbon-carbon double bond.
- Oxidative cleavage to aldehydes: the twelve-carbon internal olefin serves as a straightforward starting material when generating aldehyde products from double bond cleavage under laboratory conditions.
- Catalyst performance screening: internal alkenes are more demanding substrates than terminal alkenes, so this material gives a stricter and more informative test of catalytic activity.
- Isomerization and cis-trans selectivity studies: the internal position of the double bond makes it well suited for investigating positional migration and geometric selectivity by gas chromatography or NMR.

Handling and Storage
Store TCI D2691 5-Dodecene in its original tightly sealed container, kept in a cool, dry, and well-ventilated area away from heat, sparks, open flames, and other ignition sources. Compatible glass or manufacturer-supplied containers should be used, and closures must be resealed immediately after each withdrawal to limit evaporation and exposure to air. Handle the material in a fume hood, wearing safety goggles, chemical-resistant gloves, and a laboratory coat. Keep it separated from strong oxidizing agents, and always consult the manufacturer's safety data sheet before use, transfer, or disposal.
