Structure of Ethyl pent-4-ynoate, CAS 63093-41-4 — Structure · C7H10O2

CAS number: 63093-41-4
Molecular formula: C₇H₁₀O₂
Molecular weight: 126.15 g/mol
Standard packing: 1kg / 25kg / 100kg

Ethyl pent-4-ynoate is an ester entry in the catalogue: CAS 63093-41-4, C7H10O2, 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 formula C7H10O2 resolves to 7 carbons with 2 oxygens. At 7 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. The certificate states identity, assay and the analytical method used; a tighter limit than the catalogue entry can be written into the lot specification.
