N,N’-[1,4-Phenylenebis[(1-methylethylidene)-4,1-phenylene]]bis[1,1,1]-trifluoro-methanesulfonamide CAS 329317-98-8 chemical structure

Description

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.

CATO supplies N,N’-[1,4-Phenylenebis[(1-methylethylidene)-4,1-phenylene]]bis[1,1,1]-trifluoro-methanesulfonamide (CAS 329317-98-8), a certified reference material (molecular formula C26H26F6N2O4S2, MW 608.62 g/mol) for analytical method development and quality control.

N,N’-[1,4-Phenylenebis[(1-methylethylidene)-4,1-phenylene]]bis[1,1,1]-trifluoro-methanesulfonamide (C26H26F6N2O4S2) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), N,N’-[1,4-Phenylenebis[(1-methylethylidene)-4,1-phenylene]]bis[1,1,1]-trifluoro-methanesulfonamide 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.
