Chemical Structure

D-Glucaro-3,6-lactone CAS 2782-04-9 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.

D-Glucaro-3,6-lactone (CAS 2782-04-9) is a high-purity analytical reference standard with the molecular formula C6H8O7 and a molecular weight of 192.12 g/mol.

The molecular framework of D-Glucaro-3,6-lactone (C6H8O7) is characterized by a carbohydrate-derived structure. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

As a certified reference material (CRM), D-Glucaro-3,6-lactone 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.
