TCI M0311, (Z)-3-Methylpent-2-ene, bearing CAS number 922-62-3, is a short-chain alkene whose double bond sits at an internal position along the carbon chain, with a methyl group attached at the third carbon. It is supplied specifically as the Z (cis) geometric isomer. As a non-heterocyclic building block, this compound serves as a valuable starting material for researchers who require an olefin with a defined spatial configuration. TCI offers it in a 1 mL pack size, deliberately scaled for precision research work where what is needed is high-grade material in a small quantity.
The most defining characteristic of this product is its geometric purity. A trisubstituted double bond locked in the cis arrangement produces a steric environment and an electron density profile distinctly different from those of its trans counterpart, and as a result the rate and direction of its reactions differ as well. For researchers studying stereoselectivity, that very difference is the heart of the experiment. The electron-rich internal double bond also makes the molecule responsive to epoxidation, hydrogenation, ozonolysis, and electrophilic addition, which makes it an informative model substrate in catalyst screening and in mechanistic studies of reaction pathways.
In Indonesian laboratories, this building block finds its place in university research groups and institutional synthetic chemistry facilities where stereochemical control is a subject of active investigation. The 1 mL presentation suits settings in which experiments are run at small scale and material is consumed deliberately rather than in bulk, allowing a single unit to support an extended series of trial reactions, method development runs, and comparative stereochemical studies without oversupplying the bench.
- Stereoselectivity studies: the defined Z configuration gives researchers a substrate with known geometry, so any stereochemical outcome observed in the product can be traced back to the reaction itself rather than to an uncertain starting mixture.
- Epoxidation reactions: the electron-rich internal double bond responds readily to oxidising systems, and the fixed cis geometry allows the stereochemical course of oxygen transfer to be followed clearly across the transformation.
- Catalytic hydrogenation research: the trisubstituted alkene serves as a demanding test substrate whose sterically encumbered double bond reveals differences in catalyst activity that simpler terminal olefins would not expose.
- Ozonolysis and oxidative cleavage work: cleaving the internal double bond delivers defined carbonyl fragments, making this compound a useful reference substrate for validating cleavage procedures and analytical workup methods.
- Mechanistic investigation of electrophilic addition: the substitution pattern around the double bond influences regiochemistry and carbocation stability, so the molecule functions as an informative probe for reaction mechanism teaching and research.

Store the container tightly sealed in a cool, well-ventilated area away from direct sunlight, heat sources, and any point of ignition. Keep the material in its original supplier container, which is designed to preserve the integrity and geometric purity of the contents; if transfer is necessary, use chemically compatible glassware with a secure closure. Handle in a fume hood using appropriate personal protective equipment, including safety glasses, gloves, and a laboratory coat. Keep the compound away from strong oxidising agents and acids, minimise exposure to air during transfer, and reseal the container promptly after each use. Dispose of residues and contaminated materials in accordance with institutional chemical waste procedures.
