Structure of 1-Methyl-2-propyn-1-yl 5-hexynoate, CAS 491862-64-7 — Structure · C10H12O2

CAS number: 491862-64-7
Molecular formula: C₁₀H₁₂O₂
Molecular weight: 164.20 g/mol
Standard packing: 1kg / 25kg / 100kg

1-Methyl-2-propyn-1-yl 5-hexynoate is an alkyne entry under CAS 491862-64-7: C10H12O2, 164.20 g/mol, standard packing 1kg / 25kg / 100kg.

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 methyl branch at C1 changes how the chain packs, which shows up in melting behaviour and in the solubility of the free material.

The formula C10H12O2 resolves to 10 carbons with 2 oxygens. A 10-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

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. Release testing covers identity and assay; the impurity profile is available on request rather than being printed on this page.
