Description

3beta-[(alpha-L-Arabinopyranosyl)oxy]ursa-12,19(20)-dien-28-oic acid beta-D-glucopyranosyl ester (CAS 686776-47-6) is a high-purity analytical reference standard with the molecular formula C41H64O12 and a molecular weight of 748.94 g/mol.

The molecular framework of 3beta-[(alpha-L-Arabinopyranosyl)oxy]ursa-12,19(20)-dien-28-oic acid beta-D-glucopyranosyl ester (C41H64O12) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 3beta-[(alpha-L-Arabinopyranosyl)oxy]ursa-12,19(20)-dien-28-oic acid beta-D-glucopyranosyl ester 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.
