Chemical Structure
Description
The occurrence of 3-Bromo-5-fluoro-2-nitrotoluene is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Bromo-5-fluoro-2-nitrotoluene (CAS 1807209-40-0), molecular formula C7H5BrFNO2 and molecular weight 234.02 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Bromo-5-fluoro-2-nitrotoluene (C7H5BrFNO2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 3-Bromo-5-fluoro-2-nitrotoluene 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.
