9,9-Dibutyl-9H-fluorene-2,7-diamine CAS 1013211-64-7

Description

Compared with other compounds in its class, the molecular weight of 308.46 g/mol gives 9,9-Dibutyl-9H-fluorene-2,7-diamine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

9,9-Dibutyl-9H-fluorene-2,7-diamine (CAS 1013211-64-7) is a high-purity analytical reference standard with the molecular formula C21H28N2 and a molecular weight of 308.46 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 9,9-Dibutyl-9H-fluorene-2,7-diamine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 308.46 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.
