Chemical Structure

1,3:2,4-Bis(O-benzylidene)-D-sorbitol CAS 19046-64-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,3:2,4-Bis(O-benzylidene)-D-sorbitol.

1,3:2,4-Bis(O-benzylidene)-D-sorbitol (CAS 19046-64-1) is a high-purity analytical reference standard with the molecular formula C20H22O6 and a molecular weight of 358.39 g/mol.

Structurally, 1,3:2,4-Bis(O-benzylidene)-D-sorbitol (C20H22O6) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 358.39 g/mol, it falls into the moderately-high-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).

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