2,7-Difluoro-9H-fluorene CAS 2195-50-8

Description

Compared with other compounds in its class, the molecular weight of 310.31 g/mol gives 2,7-Difluoro-9H-fluorene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2,7-Difluoro-9H-fluorene (CAS 2195-50-8), a certified reference material (molecular formula C14H14N8O, MW 310.31 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 2,7-Difluoro-9H-fluorene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 310.31 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
