Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Heptakis(6-deoxy-6-iodo)-beta-cyclodextrin (CAS 30754-23-5), a certified reference material (molecular formula C42H63I7O28, MW 1904.26 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, a polycyclic aromatic system, Heptakis(6-deoxy-6-iodo)-beta-cyclodextrin is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1904.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
As a certified reference material (CRM), Heptakis(6-deoxy-6-iodo)-beta-cyclodextrin meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
