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-3,6-diyl)difuran.
CATO supplies 2,2'-(9,9-Dibutyl-9H-fluorene-3,6-diyl)difuran (CAS 922705-10-0), a certified reference material (molecular formula C29H30O2, MW 410.55 g/mol) for analytical method development and quality control.
Structurally, 2,2'-(9,9-Dibutyl-9H-fluorene-3,6-diyl)difuran (C29H30O2) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 410.55 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
