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 171973-69-6 2-(Acetylamino)-2-deoxy-3-O-acetyl-4,6-O-benzylidene-|A-D-galactopyranose Trichloroacetimidate 2-(Acetylamino)-2-deoxy-4,6-O-(phenylmethylene)-|A-D-galactopyranose 3-Acetate 1-(2,2,2-Trichloroethanimidate) (CAS 171973-69-6), a certified reference material (molecular formula C19H21Cl3N2O7, MW 495.74 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 171973-69-6 2-(Acetylamino)-2-deoxy-3-O-acetyl-4,6-O-benzylidene-|A-D-galactopyranose Trichloroacetimidate 2-(Acetylamino)-2-deoxy-4,6-O-(phenylmethylene)-|A-D-galactopyranose 3-Acetate 1-(2,2,2-Trichloroethanimidate) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 495.74 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
