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(2,3-diacetyl-6-sulfato)-β-cyclodextrin (CAS 196398-65-9), a certified reference material (molecular formula C70H91O70S7C5H6N, MW 2356.96 g/mol) for analytical method development and quality control.
Heptakis(2,3-diacetyl-6-sulfato)-β-cyclodextrin (C70H91O70S7C5H6N) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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(2,3-diacetyl-6-sulfato)-β-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.
