4-O-Acetyl-2,5-anhydro-1,3-O-isopropylidene-D-glucitol CAS 70128-28-8 chemical structure

Description

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

4-O-Acetyl-2,5-anhydro-1,3-O-isopropylidene-D-glucitol (CAS 70128-28-8), molecular formula C11H18O6 and molecular weight 246.26 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 4-O-Acetyl-2,5-anhydro-1,3-O-isopropylidene-D-glucitol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 246.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

CATO manufactures 4-O-Acetyl-2,5-anhydro-1,3-O-isopropylidene-D-glucitol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
