Structure of Ethyl 4,4-dimethoxybut-2-enoate, CAS 114736-25-3 — Structure · C8H14O4

CAS number: 114736-25-3
Molecular formula: C₈H₁₄O₄
Molecular weight: 174.19 g/mol
Standard packing: 1kg / 25kg / 100kg

Ethyl 4,4-dimethoxybut-2-enoate is an ester entry in the catalogue: CAS 114736-25-3, C8H14O4, packed in 1kg / 25kg / 100kg.

Methyl and ethyl esters of this size also serve as enolate equivalents in Claisen and alkylation chemistry, where the ester stabilises the carbanion. 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 C8H14O4 resolves to 8 carbons with 4 oxygens. At 8 carbons the entry is an oil or a low-melting solid, and it is handled at ambient temperature in most steps.

Handling and storage

Store neutral, dry and closed. The free acid that appears on hydrolysis is the impurity to check on a lot that has been open for months.

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. Identity is confirmed by NMR and MS at release, and the assay value belongs to the lot rather than to the catalogue entry.
