Chemical Structure

4-Bromofluoren-9-one CAS 4269-17-4 chemical structure

Description

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.

4-Bromofluoren-9-one (CAS 4269-17-4) is a high-purity analytical reference standard with the molecular formula C13H7BrO and a molecular weight of 259.10 g/mol.

Owing to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 4-Bromofluoren-9-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 259.10 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).

CATO manufactures 4-Bromofluoren-9-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
