Chemical Structure
Description
As a certified reference material (CRM), N'-(1-(phenylsulfonyl)piperidin-4-ylidene)-3-(trifluoromethyl)benzohydrazide 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.
CATO supplies N'-(1-(phenylsulfonyl)piperidin-4-ylidene)-3-(trifluoromethyl)benzohydrazide (CAS 478248-22-5), a certified reference material (molecular formula C19H18F3N3O3S, MW 425.42 g/mol) for analytical method development and quality control.
N'-(1-(phenylsulfonyl)piperidin-4-ylidene)-3-(trifluoromethyl)benzohydrazide (C19H18F3N3O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
