Chemical Structure

2,6-Dibromo-9,9-dimethyl-9H-fluorene CAS 925889-85-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 352.06 g/mol gives 2,6-Dibromo-9,9-dimethyl-9H-fluorene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2,6-Dibromo-9,9-dimethyl-9H-fluorene (CAS 925889-85-6), a certified reference material (molecular formula C15H12Br2, MW 352.06 g/mol) for analytical method development and quality control.

Structurally, 2,6-Dibromo-9,9-dimethyl-9H-fluorene (C15H12Br2) contains bromine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 352.06 g/mol, it falls into the moderately-high-molecular-weight range. 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.

CATO manufactures 2,6-Dibromo-9,9-dimethyl-9H-fluorene 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.
