Chemical Structure
Description
As a certified reference material (CRM), 6,6'-(9H-Fluorene-9,9-diyl)bis(naphthalen-2-ol) 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.
6,6'-(9H-Fluorene-9,9-diyl)bis(naphthalen-2-ol) (CAS 934557-66-1), molecular formula C33H22O2 and molecular weight 450.53 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 6,6'-(9H-Fluorene-9,9-diyl)bis(naphthalen-2-ol) (C33H22O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 23.0, corresponding to approximately 23 ring(s) or double-bond equivalent(s). With a molecular weight of 450.53 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.
