Chemical Structure
Description
(3R,4R,5R,6R)-6-(acetoxymethyl)-3-(pent-4-ynamido)tetrahydro-2H-pyran-2,4,5-triyl triacetate (CAS 1810852-60-8), molecular formula C19H25NO10 and molecular weight 427.40 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (3R,4R,5R,6R)-6-(acetoxymethyl)-3-(pent-4-ynamido)tetrahydro-2H-pyran-2,4,5-triyl triacetate (C19H25NO10) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
