Chemical Structure
Description
As a certified reference material (CRM), Cucurbit[8]uril (CB[8]) hydrate, 99+% 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.
Cucurbit[8]uril (CB[8]) hydrate, 99+% (CAS 259886-51-6) is a high-purity analytical reference standard with the molecular formula C48H48N32O16 and a molecular weight of 1329.10 g/mol.
The molecular framework of Cucurbit[8]uril (CB[8]) hydrate, 99+% (C48H48N32O16) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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).
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.
