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.

2-3-6-2’-3’-4’-6’-Hepta-O-acetyl-α-D-cellobiosyl bromide (CAS 14227-66-8) is a high-purity analytical reference standard with the molecular formula C26H35BrO17 and a molecular weight of 699.45 g/mol.

Structurally, 2-3-6-2’-3’-4’-6’-Hepta-O-acetyl-α-D-cellobiosyl bromide (C26H35BrO17) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 699.45 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
