Chemical Structure

2',7'-Dibromospiro[cyclopenta[1,2-b:5,4-b']dipyridine-5,9'-fluorene] CAS 198142-63-1 chemical structure

Description

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.

2',7'-Dibromospiro[cyclopenta[1,2-b:5,4-b']dipyridine-5,9'-fluorene] (CAS 198142-63-1) is a high-purity analytical reference standard with the molecular formula C23H12Br2N2 and a molecular weight of 476.16 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution, 2',7'-Dibromospiro[cyclopenta[1,2-b:5,4-b']dipyridine-5,9'-fluorene] is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 476.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
