Chemical Structure
Description
CATO supplies 2',7'-Dibromo-5H-spiro[dibenzo[c,h]acridine-7,9'-fluoren]-5-one (CAS 1345890-47-2), a certified reference material (molecular formula C33H17Br2NO, MW 603.30 g/mol) for analytical method development and quality control.
Structurally, 2',7'-Dibromo-5H-spiro[dibenzo[c,h]acridine-7,9'-fluoren]-5-one (C33H17Br2NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 25.0, corresponding to approximately 25 ring(s) or double-bond equivalent(s). With a molecular weight of 603.30 g/mol, it falls into the high-molecular-weight range. 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.
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.
