Description
CATO supplies [4-Bromo-2-(trifluoromethyl)phenyl]hydrazine (CAS 312303-71-2), a certified reference material (molecular formula C7H6BrF3N2, MW 255.04 g/mol) for analytical method development and quality control.
Owing to a nitrile group, fluorine/bromine substitution, an aromatic ring system, [4-Bromo-2-(trifluoromethyl)phenyl]hydrazine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 255.04 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), [4-Bromo-2-(trifluoromethyl)phenyl]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.
