As a certified reference material (CRM), 2,2'-((((Oxybis(ethane-2,1-diyl))bis(oxy))bis(4,1-phenylene))bis(methaneylylidene))bis(1-phenylhydrazine) 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 2,2'-((((Oxybis(ethane-2,1-diyl))bis(oxy))bis(4,1-phenylene))bis(methaneylylidene))bis(1-phenylhydrazine) (CAS 203805-28-1), a certified reference material (molecular formula C30H30N4O3, MW 494.58 g/mol) for analytical method development and quality control.
2,2'-((((Oxybis(ethane-2,1-diyl))bis(oxy))bis(4,1-phenylene))bis(methaneylylidene))bis(1-phenylhydrazine) (C30H30N4O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
