Structure of Pent-4-yn-1-ol, CAS 5390-04-5 — Structure · C5H8O

CAS number: 5390-04-5
Molecular formula: C₅H₈O
Molecular weight: 84.12 g/mol
Standard packing: 1kg / 25kg / 100kg

CAS 5390-04-5, Pent-4-yn-1-ol, enters the catalogue as a C5H8O alkyne with a molecular weight of 84.12.

The terminal C-H is the reactive end: it is metalated and trapped, coupled under Sonogashira conditions, or cycloadded with an azide in a copper-catalysed reaction.

The formula C5H8O resolves to 5 carbons with one oxygen. With 5 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

Packing 1kg / 25kg / 100kg, with the batch COA, the SDS and a specification sheet suitable for incoming inspection travelling with the lot.
