Description

CATO supplies (2R,3R,4S,5R,6R)-2-(((2S,3S,4R,5R)-2,5-bis(hydroxymethyl)-3,4-bis((3-methylbutanoyl)oxy)tetrahydrofuran-2-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triyl tris(3-methylbutanoate) (CAS 498552-73-1), a certified reference material (molecular formula C37H62O16, MW 762.88 g/mol) for analytical method development and quality control.

Structurally, (2R,3R,4S,5R,6R)-2-(((2S,3S,4R,5R)-2,5-bis(hydroxymethyl)-3,4-bis((3-methylbutanoyl)oxy)tetrahydrofuran-2-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triyl tris(3-methylbutanoate) (C37H62O16) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 762.88 g/mol, it falls into the high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
