Can 1-Chloro-2-methyl-1-cyclohexene be identified by molecular formula alone?

No. The formula C7H11Cl can describe multiple constitutional isomers. This name specifies chlorine at ring position 1, a methyl group at position 2 and the double bond between those positions. Confirm the full name, CAS 16642-49-2, structure and an agreed GC or spectral identity method.

1-Chloro-2-methyl-1-cyclohexene CAS 16642-49-2

1-Chloro-2-methyl-1-cyclohexene, CAS 16642-49-2, is a cyclic chloroalkene intermediate bearing chlorine on a vinylic carbon, with molecular formula C7H11Cl and molecular weight 130.62 g/mol. It is offered for controlled research and organic-synthesis projects rather than under a universal industrial 99% specification. Predicted boiling point, flash point or density values should be clearly distinguished from lot-release data. Buyers should qualify the offered grade by identity, chromatographic assay, isomer or impurity profile, physical form and reaction performance.

CAS: 16642-49-2
Synonyms: 1-Chloro-2-methyl-1-cyclohexene, 1-Chloro-2-methylcyclohexene, Cyclohexene, 1-chloro-2-methyl-
Molecular Formula: C₇H₁₁Cl
Grade: Confirm identity, assay method, water or residual solvents, product-specific impurities and physical form against the current COA; no end-use grade is assumed.
Package: State required quantity and destination; confirm the approved container or cylinder, inerting or stabilizer needs, closure or valve, fill quantity, temperature controls and dangerous-goods requirements against the SDS.

Applications and grade selection

This chloroalkene is evaluated as a building block in controlled substitution, elimination, coupling and other organic transformations where its cyclic unsaturated framework is required. Suitability depends on the actual route, catalyst, solvent, impurity tolerance and downstream specification.

Agree the identity and chromatographic methods plus any route-critical isomer or impurity limits.
Qualify conversion, selectivity, work-up and final-product quality in the buyer’s actual reaction.
Confirm physical form, sample size, compatible packaging, transport status and storage conditions before ordering.

Storage and handling

Keep the original container tightly closed in a cool, dry, ventilated area away from ignition sources and incompatible oxidizing materials. Follow the current SDS for temperature, grounding, transfer and spill-control requirements.

Safety, documentation and procurement

Handle with suitable gloves, eye protection and ventilation and control ignition sources according to the supplied SDS. A quotation request should include the required assay, impurity profile, reaction, quantity, package, destination and documents.
