Chemical Structure
Description
3-O-Benzyl-1,2-O-isopropylidene-a-D-glucofuranose (CAS 22529-61-9), molecular formula C16H22O6 and molecular weight 310.34 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-O-Benzyl-1,2-O-isopropylidene-a-D-glucofuranose (C16H22O6) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 310.34 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
