Chemical Structure
Description
The occurrence of 7-Bromo-9,9-dimethyl-9H-fluorene-2-carbaldehyde is closely related to a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 7-Bromo-9,9-dimethyl-9H-fluorene-2-carbaldehyde (CAS 944940-90-3), a certified reference material (molecular formula C16H13BrO, MW 301.18 g/mol) for analytical method development and quality control.
The molecular framework of 7-Bromo-9,9-dimethyl-9H-fluorene-2-carbaldehyde (C16H13BrO) is characterized by a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 7-Bromo-9,9-dimethyl-9H-fluorene-2-carbaldehyde 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.
