Compared with other compounds in its class, the molecular weight of 568.66 g/mol gives Methyl 2,3,4-Tri-O-benzyl-α-D-glucuronic Acid, Benzyl Ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Methyl 2,3,4-Tri-O-benzyl-α-D-glucuronic Acid, Benzyl Ester (CAS 142797-33-9), a certified reference material (molecular formula C35H36O7, MW 568.66 g/mol) for analytical method development and quality control.
Structurally, Methyl 2,3,4-Tri-O-benzyl-α-D-glucuronic Acid, Benzyl Ester (C35H36O7) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 18.0, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 568.66 g/mol, it falls into the moderately-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.
