Structure of 3-Ethoxyprop-1-yne, CAS 628-33-1 — Structure · C5H8O

CAS number: 628-33-1
Molecular formula: C₅H₈O
Molecular weight: 84.12 g/mol
Standard packing: 1kg / 25kg / 100kg

3-Ethoxyprop-1-yne (CAS 628-33-1) is a C5H8O alkyne building block supplied in kilogram lots.

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 C5H8O resolves to 5 carbons with one oxygen. Short-chain entries of this size are volatile enough that headspace and packing matter: the lot is shipped in sealed units and opened in a fume hood.

Handling and storage

Alkynes are held closed, dry and out of direct light; the silylated entries are also moisture sensitive and are packed under inert gas.

Ordering

Shipped in 1kg / 25kg / 100kg units with a batch certificate of analysis and a GHS safety data sheet; a smaller sample can be quoted separately. Nothing on this page should be read as a guaranteed minimum. The number that applies is the one on the certificate for the lot you receive.
