Structure of Methyl 2-Propynyl Ether, CAS 627-41-8 — Structure · C4H6O

CAS number: 627-41-8
Molecular formula: C₄H₆O
Molecular weight: 70.09 g/mol
Standard packing: 1kg / 25kg / 100kg

Catalogued as CAS 627-41-8, Methyl 2-Propynyl Ether is a C4H6O alkyne carried in kilogram quantities.

Terminal alkynes also dimerise and oligomerise under the wrong conditions, so the copper and palladium loading of the coupling step is the thing to control.

The formula C4H6O resolves to 4 carbons with one oxygen. With 4 carbons the molecule is small enough to be lost to evaporation during a work-up, so the step is usually run closed.

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

Quoted from stock in 1kg / 25kg / 100kg, or made to order where the lot has run down. Either way the same release testing applies. Where a specification has to be met on paper before shipment, it is agreed in writing and the lot is qualified against it rather than against the catalogue text.
