Spiro[9<I>H</I>-fluorene-9,9′-[9<I>H</I>]xanthene]-2,2′,7,7′-tetramine CAS 1887794-22-0

Description

The occurrence of Spiro[9<I>H</I>-fluorene-9,9′-[9<I>H</I>]xanthene]-2,2′,7,7′-tetramine is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Spiro[9<I>H</I>-fluorene-9,9′-[9<I>H</I>]xanthene]-2,2′,7,7′-tetramine (CAS 1887794-22-0), molecular formula C81H68N4O9 and molecular weight 1241.43 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Spiro[9<I>H</I>-fluorene-9,9′-[9<I>H</I>]xanthene]-2,2′,7,7′-tetramine (C81H68N4O9) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
