Chemical Structure
Description
2-(Bis(4-bromobenzyl)amino)-9H-fluoren-9-one (CAS 96176-12-4), molecular formula C20H16O3 and molecular weight 304.34 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-(Bis(4-bromobenzyl)amino)-9H-fluoren-9-one (C20H16O3) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 304.34 g/mol, it falls into the moderately-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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 2-(Bis(4-bromobenzyl)amino)-9H-fluoren-9-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
