900019-36-5 KS-0000204K N'-[(E)-(4-bromo-3-thienyl)methylidene]-4-(trifluoromethyl)benzenecarbohydrazide CAS 900019-36-5

Description

900019-36-5 KS-0000204K N'-[(E)-(4-bromo-3-thienyl)methylidene]-4-(trifluoromethyl)benzenecarbohydrazide (CAS 900019-36-5) is a high-purity analytical reference standard with the molecular formula C13H8BrF3N2OS and a molecular weight of 377.18 g/mol.

900019-36-5 KS-0000204K N'-[(E)-(4-bromo-3-thienyl)methylidene]-4-(trifluoromethyl)benzenecarbohydrazide (C13H8BrF3N2OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 900019-36-5 KS-0000204K N'-[(E)-(4-bromo-3-thienyl)methylidene]-4-(trifluoromethyl)benzenecarbohydrazide 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.
