Chemical Structure
Description
As a certified reference material (CRM), (E)-N'-(4-Bromobenzylidene)-2-(trifluoromethyl)benzenesulfonohydrazide 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.
(E)-N'-(4-Bromobenzylidene)-2-(trifluoromethyl)benzenesulfonohydrazide (CAS 2301998-80-9) is a high-purity analytical reference standard with the molecular formula C14H10BrF3N2O2S and a molecular weight of 407.21 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, (E)-N'-(4-Bromobenzylidene)-2-(trifluoromethyl)benzenesulfonohydrazide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 407.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
