Description

As a certified reference material (CRM), (3R,4S,5R,6R)-6-(acetoxymethyl)-5-(((2S,3R,4S,5R,6R)-3,4-diacetoxy-6-(acetoxymethyl)-5-(((2S,3R,4S,5R,6R)-3,4,5-triacetoxy-6-(acetoxymethyl)tetrahydro-2H-pyran-2-yl)oxy)tetrahydro-2H-pyran-2-yl)oxy)tetrahydro-2H-pyran-2,3,4-triyl triacetate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

(3R,4S,5R,6R)-6-(acetoxymethyl)-5-(((2S,3R,4S,5R,6R)-3,4-diacetoxy-6-(acetoxymethyl)-5-(((2S,3R,4S,5R,6R)-3,4,5-triacetoxy-6-(acetoxymethyl)tetrahydro-2H-pyran-2-yl)oxy)tetrahydro-2H-pyran-2-yl)oxy)tetrahydro-2H-pyran-2,3,4-triyl triacetate (CAS 17690-94-7), molecular formula C40H54O27 and molecular weight 966.84 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (3R,4S,5R,6R)-6-(acetoxymethyl)-5-(((2S,3R,4S,5R,6R)-3,4-diacetoxy-6-(acetoxymethyl)-5-(((2S,3R,4S,5R,6R)-3,4,5-triacetoxy-6-(acetoxymethyl)tetrahydro-2H-pyran-2-yl)oxy)tetrahydro-2H-pyran-2-yl)oxy)tetrahydro-2H-pyran-2,3,4-triyl triacetate (C40H54O27) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 966.84 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.
