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.

methyl (1R,3R,4R,5S)-3-[(2R,3R,4R,5R,6R)-3-(allyloxycarbonylamino)-4,5-dihydroxy-6-(hydroxymethyl)tetrahydropyran-2-yl]oxy-5-ethyl-4-[(2S,3S,4R,5R,6S)-3,4,5-tribenzyloxy-6-methyl-tetrahydropyran-2-yl]oxy-cyclohexanecarboxylate (CAS 2609644-29-1), molecular formula C47H79NO14 and molecular weight 882.13 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of methyl (1R,3R,4R,5S)-3-[(2R,3R,4R,5R,6R)-3-(allyloxycarbonylamino)-4,5-dihydroxy-6-(hydroxymethyl)tetrahydropyran-2-yl]oxy-5-ethyl-4-[(2S,3S,4R,5R,6S)-3,4,5-tribenzyloxy-6-methyl-tetrahydropyran-2-yl]oxy-cyclohexanecarboxylate (C47H79NO14) is characterized by a nitrogen-containing heterocyclic scaffold, 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 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).

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.
