Chemical Structure
Description
As a certified reference material (CRM), 4'-Carboxybenzo-18-crown-6, 97% 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.
CATO supplies 4'-Carboxybenzo-18-crown-6, 97% (CAS 60835-75-8), a certified reference material (molecular formula C17H24O8, MW 356.37 g/mol) for analytical method development and quality control.
The molecular framework of 4'-Carboxybenzo-18-crown-6, 97% (C17H24O8) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring 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.
