Chemical Structure
Description
As a certified reference material (CRM), N-(9H-Fluoren-2-yl)-N-hydroxybenzamide 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.
N-(9H-Fluoren-2-yl)-N-hydroxybenzamide (CAS 3671-71-4), molecular formula C20H15NO2 and molecular weight 301.34 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(9H-Fluoren-2-yl)-N-hydroxybenzamide (C20H15NO2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
