Description
CATO manufactures Heptakis-(2,6-di-O-ethyl)-β-cyclodextrin under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies Heptakis-(2,6-di-O-ethyl)-β-cyclodextrin (CAS 111689-03-3), a certified reference material (molecular formula C70H126O35, MW 1527.73 g/mol) for analytical method development and quality control.
The molecular framework of Heptakis-(2,6-di-O-ethyl)-β-cyclodextrin (C70H126O35) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
