CATO supplies N-(2-Hydrazinyl-2-oxoethyl)benzo[c][1,2,5]thiadiazole-4-sulfonamide (CAS 175203-26-6), a certified reference material (molecular formula C8H9N5O3S2, MW 287.32 g/mol) for analytical method development and quality control.
The molecular framework of N-(2-Hydrazinyl-2-oxoethyl)benzo[c][1,2,5]thiadiazole-4-sulfonamide (C8H9N5O3S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
