Chemical Structure

Ethyl 3,4,6-tri-O-Acetyl-2-deoxy-2-phthalimido-β-D-thioglucopyranoside CAS 99409-32-2 chemical structure

Description

The occurrence of Ethyl 3,4,6-tri-O-Acetyl-2-deoxy-2-phthalimido-β-D-thioglucopyranoside is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethyl 3,4,6-tri-O-Acetyl-2-deoxy-2-phthalimido-β-D-thioglucopyranoside (CAS 99409-32-2) is a high-purity analytical reference standard with the molecular formula C22H25NO9S and a molecular weight of 479.50 g/mol.

Ethyl 3,4,6-tri-O-Acetyl-2-deoxy-2-phthalimido-β-D-thioglucopyranoside (C22H25NO9S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Ethyl 3,4,6-tri-O-Acetyl-2-deoxy-2-phthalimido-β-D-thioglucopyranoside 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.
