Chemical Structure
Description
2-3-6-2-3-4-6-Hepta-O-acetyl-β-D-cellobiosyl azide (CAS 33012-50-9) is a high-purity analytical reference standard with the molecular formula C26H35N3O17 and a molecular weight of 661.57 g/mol.
Structurally, 2-3-6-2-3-4-6-Hepta-O-acetyl-β-D-cellobiosyl azide (C26H35N3O17) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 661.57 g/mol, it falls into the high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
