Catalogued as CAS 5272-36-6, 3-(Trimethylsilyl)propargyl alcohol is a C6H12OSi alkyne carried in kilogram quantities.
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 protecting group is the reason the entry exists: it is carried through the steps that would otherwise attack the group underneath, and removed when that group is wanted.
The formula C6H12OSi resolves to 6 carbons with one oxygen and one silicon. With 6 carbons the molecule is small enough to be lost to evaporation during a work-up, so the step is usually run closed.
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
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.
