1-Fluoro-7-nitro-9H-fluorene CAS 343-38-4

Description

Compared with other compounds in its class, the molecular weight of 275.35 g/mol gives 1-Fluoro-7-nitro-9H-fluorene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-Fluoro-7-nitro-9H-fluorene (CAS 343-38-4), molecular formula C15H21N3O2 and molecular weight 275.35 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 1-Fluoro-7-nitro-9H-fluorene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 275.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
