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 (2R,3R,4S,5R)-2-(acetoxymethyl)-6-ethoxytetrahydro-2H-pyran-3,4,5-triyl triacetate (CAS CATO-C3D-262410), a certified reference material (molecular formula C16H24O10, MW 376.36 g/mol) for analytical method development and quality control.
Structurally, (2R,3R,4S,5R)-2-(acetoxymethyl)-6-ethoxytetrahydro-2H-pyran-3,4,5-triyl triacetate (C16H24O10) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 376.36 g/mol, it falls into the moderately-high-molecular-weight range. 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.
