Structure of 2-Methyl-4-phenyl-3-butyn-2-ol, CAS 1719-19-3 — Structure · C11H12O

CAS number: 1719-19-3
Molecular formula: C₁₁H₁₂O
Molecular weight: 160.21 g/mol
Standard packing: 1kg / 25kg / 100kg

Catalogued as CAS 1719-19-3, 2-Methyl-4-phenyl-3-butyn-2-ol is a C11H12O alkyne carried in kilogram quantities.

Partial hydrogenation, cycloaddition and alkyne metathesis are the reactions this entry is bought for, and the substitution pattern is what makes them selective. The methyl branch at C2 changes how the chain packs, which shows up in melting behaviour and in the solubility of the free material.

The formula C11H12O resolves to 11 carbons with one oxygen. At 11 carbons the entry is an oil or a low-melting solid, and it is handled at ambient temperature in most steps.

Handling and storage

The container is kept sealed and out of light. Alkynes are checked for the coupled diyne before use, because that is the impurity that builds on standing.

Ordering

Standard packing 1kg / 25kg / 100kg. Other unit weights are quoted per lot and confirmed in writing before the material is packed. Release testing covers identity and assay; the impurity profile is available on request rather than being printed on this page.
