Chemical Structure

Heptakis(2,3,6-tri-O-methyl)-β-cyclodextrin CAS 55216-11-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 1429.54 g/mol gives Heptakis(2,3,6-tri-O-methyl)-β-cyclodextrin distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Heptakis(2,3,6-tri-O-methyl)-β-cyclodextrin (CAS 55216-11-0) is a high-purity analytical reference standard with the molecular formula C63H112O35 and a molecular weight of 1429.54 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Heptakis(2,3,6-tri-O-methyl)-β-cyclodextrin is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1429.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
