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.
- 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.
FAQ - Technical & Supply Chain
-
Q:
Can 1-Chloro-2-methyl-1-cyclohexene be identified by molecular formula alone?
A: 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.
