Chemical Structure
Description
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.
CATO supplies 1,3-Dibenzyl-4-(((tert-butyldimethylsilyl)oxy)methyl)-5-(6-hydroxy-1-((triethylsilyl)oxy)hexyl)imidazolidin-2-one (CAS 1796891-26-3), a certified reference material (molecular formula C36H60N2O4Si2, MW 641.04 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 1,3-Dibenzyl-4-(((tert-butyldimethylsilyl)oxy)methyl)-5-(6-hydroxy-1-((triethylsilyl)oxy)hexyl)imidazolidin-2-one is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 641.04 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).
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.
