Chemical Structure

2,3,4,6-Tetra-O-acetyl-|A-D-glucopyranosyl Salicylate 2-[(2,3,4,6-Tetra-O-acetyl-|A-D-glucopyranosyl)oxy]-benzoic Acid 33019-34-0 Tetraacetate o-(|A-D-Glucopyranosyloxy)-benzoic Acid CAS 33019-34-0 chemical structure

Description

The molecular framework of 2,3,4,6-Tetra-O-acetyl-|A-D-glucopyranosyl Salicylate 2-[(2,3,4,6-Tetra-O-acetyl-|A-D-glucopyranosyl)oxy]-benzoic Acid 33019-34-0 Tetraacetate o-(|A-D-Glucopyranosyloxy)-benzoic Acid (C21H24O12) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. 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).

2,3,4,6-Tetra-O-acetyl-|A-D-glucopyranosyl Salicylate 2-[(2,3,4,6-Tetra-O-acetyl-|A-D-glucopyranosyl)oxy]-benzoic Acid 33019-34-0 Tetraacetate o-(|A-D-Glucopyranosyloxy)-benzoic Acid (CAS 33019-34-0) is a high-purity analytical reference standard with the molecular formula C21H24O12 and a molecular weight of 468.41 g/mol.

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

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
