Can a mixed-isomer 2-Octene grade replace cis-2-Octene CAS 7642-04-8?

Not without confirming the required geometric-isomer specification. CAS 7642-04-8 identifies the cis (Z) isomer, while mixed 2-octene materials can have different cis/trans ratios and different physical or reaction behavior. Compare the GC method, cis assay, trans limit and any limits for other octene isomers.

cis-2-Octene CAS 7642-04-8

cis-2-Octene (CAS 7642-04-8), also called (Z)-2-Octene or (Z)-Oct-2-ene, is a stereochemically defined internal olefin for controlled organic synthesis and reaction-mechanism studies. Analytical or calibration use requires suitable characterization and traceability. GC assay and cis-isomer content are separate specification points, alongside trans-isomer and other hydrocarbon levels, water content and physical form. COA, TDS and SDS are available for specification review and handling guidance.

CAS: 7642-04-8

Identity and physicochemical profile

Item	Technical guidance
Correct identity	cis-2-Octene; (Z)-2-octene
CAS / EC	7642-04-8 / 231-577-9
Formula / molecular weight	C₈H₁₆ / 112.21 g/mol
Stereochemical boundary	The cis or Z isomer is distinct from trans-2-octene and unspecified 2-octene mixtures
Key controls	GC assay, cis-isomer content, trans isomer, other hydrocarbons, water where relevant and physical appearance
Physical character	Volatile flammable hydrocarbon liquid; exact release and transport data follow the offered grade and SDS

Applications and grade selection

cis-2-Octene is evaluated as a stereochemically defined internal olefin for controlled organic synthesis, reaction-mechanism work and selected analytical or calibration projects.

Define both total GC assay and minimum cis-isomer content; these are not interchangeable specifications.
Compare reaction conversion, stereochemical outcome and impurity carryover using the buyer’s actual process.
For analytical use, define characterization and traceability requirements beyond a routine bulk COA.

Storage and handling

Keep the container tightly closed in a cool, dry, ventilated area away from heat, sparks, flame and oxidizers. Use grounded, compatible transfer equipment and follow the current SDS for flammable-liquid storage and transport.

Safety, documentation and procurement

Control ignition sources and vapors, and use suitable gloves, eye protection and ventilation according to the current SDS. Procurement should state GC and isomer limits, use, quantity, package, destination, shipping terms and documents.
