Chemical Structure

1,2:3,4-DI-o-isopropylidene-l-arabinopyranose CAS 212069-31-3 chemical structure

Description

Structurally, 1,2:3,4-DI-o-isopropylidene-l-arabinopyranose (C11H18O5) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 230.26 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

1,2:3,4-DI-o-isopropylidene-l-arabinopyranose (CAS 212069-31-3), molecular formula C11H18O5 and molecular weight 230.26 g/mol, is a CATO reference standard with documented purity and traceability.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 1,2:3,4-DI-o-isopropylidene-l-arabinopyranose meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
