2-Bromo-7-chloro-9H-fluorene CAS 99586-26-2

Description

The occurrence of 2-Bromo-7-chloro-9H-fluorene is closely related to chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Bromo-7-chloro-9H-fluorene (CAS 99586-26-2) is a high-purity analytical reference standard with the molecular formula C13H8BrCl and a molecular weight of 279.56 g/mol.

Owing to chlorine/bromine substitution, an aromatic ring system, 2-Bromo-7-chloro-9H-fluorene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 279.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), 2-Bromo-7-chloro-9H-fluorene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
