Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,2'-(9,9-Dibutyl-9H-fluorene-2,7-diyl)difuran.
2,2'-(9,9-Dibutyl-9H-fluorene-2,7-diyl)difuran (CAS 922705-11-1), molecular formula C29H30O2 and molecular weight 410.55 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, a hydroxyl group, an ether linkage, 2,2'-(9,9-Dibutyl-9H-fluorene-2,7-diyl)difuran is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 410.55 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 2,2'-(9,9-Dibutyl-9H-fluorene-2,7-diyl)difuran 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.
