Structure of 4,4-diethoxybut-2-ynal, CAS 74149-25-0 — Structure · C8H12O3

CAS number: 74149-25-0
Molecular formula: C₈H₁₂O₃
Molecular weight: 156.18 g/mol
Standard packing: 1kg / 25kg / 100kg

4,4-diethoxybut-2-ynal (CAS 74149-25-0) is an aldehyde building block of formula C8H12O3, 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 acetal is a masked carbonyl. It survives base and hydride conditions and is opened under acid, which is what makes it useful in the middle of a sequence.

The formula C8H12O3 resolves to 8 carbons with 3 oxygens. A 8-carbon chain sits between volatility and lipophilicity, which is the range most often used when a fragment has to stay in the organic phase without being waxy.

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.
