Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 542.64 g/mol gives 2-3-4-6-Tetra-O-benzyl-D-glucopyranosyl fluoride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-3-4-6-Tetra-O-benzyl-D-glucopyranosyl fluoride (CAS 122741-44-0), molecular formula C34H35FO5 and molecular weight 542.64 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-3-4-6-Tetra-O-benzyl-D-glucopyranosyl fluoride (C34H35FO5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 17.0, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 542.64 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.
