Chemical Structure
Description
CATO supplies 17β-Estradiol-d3 3-β-D-Glucuronide (CAS 1260231-06-8), a certified reference material (molecular formula C24H29D3O8, MW 451.52 g/mol) for analytical method development and quality control.
Owing to deuterium isotope labeling, a flavonoid core, a hydroxyl group, an ether linkage, 17β-Estradiol-d3 3-β-D-Glucuronide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 451.52 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).
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), 17β-Estradiol-d3 3-β-D-Glucuronide 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.
