Rehmannioside D CAS 81720-08-3 chemical structure

Description

CATO manufactures Rehmannioside D under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

CATO supplies Rehmannioside D (CAS 81720-08-3), a certified reference material (molecular formula C27H42O20, MW 686.61 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Rehmannioside D is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 686.61 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
