Description

Compared with other compounds in its class, the molecular weight of 1541.54 g/mol gives Heptakis-O-(2-Hydroxypropyl)-β-cyclodextrin distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Heptakis-O-(2-Hydroxypropyl)-β-cyclodextrin (CAS 136019-12-0), molecular formula C63H112O42 and molecular weight 1541.54 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Heptakis-O-(2-Hydroxypropyl)-β-cyclodextrin (C63H112O42) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
