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.
N-((2S,3R,4R,5S,6R)-2-((5-Bromo-6-chloro-1H-indol-3-yl)oxy)-4,5-dihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide (CAS 5609-91-6) is a high-purity analytical reference standard with the molecular formula C16H18BrClN2O6 and a molecular weight of 449.68 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, N-((2S,3R,4R,5S,6R)-2-((5-Bromo-6-chloro-1H-indol-3-yl)oxy)-4,5-dihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 449.68 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.
