Chemical Structure
Description
Diethyl 2,2'-((32,72-dihydroxy-1,3,5,7(1,3)-tetrabenzenacyclooctaphane-12,52-diyl)bis(oxy))diacetate (CAS 142267-55-8) is a high-purity analytical reference standard with the molecular formula C36H36O8 and a molecular weight of 596.67 g/mol.
The molecular framework of Diethyl 2,2'-((32,72-dihydroxy-1,3,5,7(1,3)-tetrabenzenacyclooctaphane-12,52-diyl)bis(oxy))diacetate (C36H36O8) 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.
As a certified reference material (CRM), Diethyl 2,2'-((32,72-dihydroxy-1,3,5,7(1,3)-tetrabenzenacyclooctaphane-12,52-diyl)bis(oxy))diacetate 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.
