1,2:4,5-Di-O-isopropylidene-D,L-myo-inositol (CAS 98974-89-1) is an unsaturated building block of formula C12H20O6, 260.28 g/mol.

The double bond is the handle: epoxidation, dihydroxylation, hydrogenation and cross-metathesis all start here. A single enantiomer is named, which is why the entry is quoted separately from the racemic version of the same skeleton.

The formula C12H20O6 resolves to 12 carbons with 6 oxygens. A 12-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

Olefins are stored closed and out of light; the isomer ratio is checked on receipt because it can drift on storage.

Ordering

The unit weights held are 1kg / 25kg / 100kg. A split shipment across two of those sizes is treated as one lot and one certificate. The certificate states identity, assay and the analytical method used; a tighter limit than the catalogue entry can be written into the lot specification.
