Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 210.07 g/mol gives 4-Bromo-2,6-dimethylbenzonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Bromo-2,6-dimethylbenzonitrile (CAS 5757-66-4), a certified reference material (molecular formula C9H8BrN, MW 210.07 g/mol) for analytical method development and quality control.
The molecular framework of 4-Bromo-2,6-dimethylbenzonitrile (C9H8BrN) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 4-Bromo-2,6-dimethylbenzonitrile 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.
