Chemical Structure

Aloe-emodin-3-(hydroxymethyl)-O-beta-D-glucopyranoside CAS 50488-89-6 chemical structure

Description

The occurrence of Aloe-emodin-3-(hydroxymethyl)-O-beta-D-glucopyranoside is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Aloe-emodin-3-(hydroxymethyl)-O-beta-D-glucopyranoside (CAS 50488-89-6), a certified reference material (molecular formula C21H20O10, MW 432.38 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, Aloe-emodin-3-(hydroxymethyl)-O-beta-D-glucopyranoside is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 432.38 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).

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.
