3-Butynyl tetrahydro-2H-pyran-2-yl ether

CAS 40365-61-5, 3-Butynyl tetrahydro-2H-pyran-2-yl ether, enters the catalogue as a C9H14O2 alkyne with a molecular weight of 154.21.

Partial hydrogenation, cycloaddition and alkyne metathesis are the reactions this entry is bought for, and the substitution pattern is what makes them selective. The ring constrains the geometry of the fragment, so the entry is bought for the shape it imposes on the rest of the molecule rather than for a single reactive site.

The formula C9H14O2 resolves to 9 carbons with 2 oxygens. At 9 carbons the entry is an oil or a low-melting solid, and it is handled at ambient temperature in most steps.

Handling and storage

The container is kept sealed and out of light. Alkynes are checked for the coupled diyne before use, because that is the impurity that builds on standing.

Ordering

Standard packing 1kg / 25kg / 100kg. Other unit weights are quoted per lot and confirmed in writing before the material is packed. Release testing covers identity and assay; the impurity profile is available on request rather than being printed on this page.
