Chemical Structure

9H-Fluorene-2,9-diamine CAS 7148-37-0 chemical structure

Description

As a certified reference material (CRM), 9H-Fluorene-2,9-diamine 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.

9H-Fluorene-2,9-diamine (CAS 7148-37-0), molecular formula C13H12N2 and molecular weight 196.25 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 9H-Fluorene-2,9-diamine (C13H12N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 196.25 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
