Structure of 3-Methylbut-2-enal, CAS 107-86-8 — Structure · C5H8O

CAS number: 107-86-8
Molecular formula: C₅H₈O
Molecular weight: 84.12 g/mol
Standard packing: 1kg / 25kg / 100kg

3-Methylbut-2-enal (CAS 107-86-8) is an aldehyde building block of formula C5H8O, supplied in kilogram lots.

The aldehyde carbon is electrophilic, so reductive amination, Wittig olefination and aldol addition are the usual entry points into a route. The methyl branch at C3 changes how the chain packs, which shows up in melting behaviour and in the solubility of the free material.

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

Aldehydes oxidise in air. The container is kept closed with a small headspace, and the lot is used soon after opening.

Ordering

Supplied in 1kg / 25kg / 100kg; a gram-scale sample is quoted against the same specification, so the analysis seen at sample stage is the analysis of the kilo lot.
