Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 217.04 g/mol gives (5-Bromo-2-fluorobenzylidene)hydrazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (5-Bromo-2-fluorobenzylidene)hydrazine (CAS 710292-26-5), a certified reference material (molecular formula C7H6BrFN2, MW 217.04 g/mol) for analytical method development and quality control.
(5-Bromo-2-fluorobenzylidene)hydrazine (C7H6BrFN2) contains a nitrile group, fluorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), (5-Bromo-2-fluorobenzylidene)hydrazine 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.
