Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 17β-Estradiol 3-O-Benzyl 17-(2,3,4-Tri-O-acetyl-β-D-glucuronide Methyl Ester) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 678.77 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).
17β-Estradiol 3-O-Benzyl 17-(2,3,4-Tri-O-acetyl-β-D-glucuronide Methyl Ester) (CAS 14364-98-8) is a high-purity analytical reference standard with the molecular formula C38H46O11 and a molecular weight of 678.77 g/mol.
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.
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.
