Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Heptakis(2,3-di-O-acetyl-6-sulfo)-beta-cyclodextrin sodium salt.
CATO supplies Heptakis(2,3-di-O-acetyl-6-sulfo)-beta-cyclodextrin sodium salt (CAS 196398-66-0), a certified reference material (molecular formula C70H91O70S7Na, MW 2299.84 g/mol) for analytical method development and quality control.
The molecular framework of Heptakis(2,3-di-O-acetyl-6-sulfo)-beta-cyclodextrin sodium salt (C70H91O70S7Na) is characterized by a sulfone group, 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).
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.
CATO manufactures Heptakis(2,3-di-O-acetyl-6-sulfo)-beta-cyclodextrin sodium salt 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.
