Description

39941-51-0 Uttronin A beta-D-Galactopyranoside, (3beta,5alpha,25R)-spirostan-3-yl O-beta-D-glucopyranosyl-(1-2)-O-(beta-D-xylopyranosyl-(1-3))-O-beta-D-glucopyranosyl-(1-4)- 3-O-(beta-Lycotetraosyl)-(25R)-5alpha-spirostan-3beta-ol (3beta,5alpha,25R)-Spirostan-3-yl O-beta-D-glucopyranosyl-(1-2)-O-(beta-D-xylopyranosyl-(1-3))-O-beta-D-glucopyranosyl-(1-4)-beta-D-galactopyranoside (CAS 39941-51-0), molecular formula C50H82O22 and molecular weight 1035.17 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 39941-51-0 Uttronin A beta-D-Galactopyranoside, (3beta,5alpha,25R)-spirostan-3-yl O-beta-D-glucopyranosyl-(1-2)-O-(beta-D-xylopyranosyl-(1-3))-O-beta-D-glucopyranosyl-(1-4)- 3-O-(beta-Lycotetraosyl)-(25R)-5alpha-spirostan-3beta-ol (3beta,5alpha,25R)-Spirostan-3-yl O-beta-D-glucopyranosyl-(1-2)-O-(beta-D-xylopyranosyl-(1-3))-O-beta-D-glucopyranosyl-(1-4)-beta-D-galactopyranoside (C50H82O22) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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).

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.
