Description
As a certified reference material (CRM), Dinaphtho[2,1-b:1,2-d]furan 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.
Dinaphtho[2,1-b:1,2-d]furan (CAS 194-63-8), molecular formula C20H12O and molecular weight 268.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Dinaphtho[2,1-b:1,2-d]furan (C20H12O) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
