Description
Compared with other compounds in its class, the molecular weight of 404.49 g/mol gives N-(2-(3-(Pyridin-4-yl)-4,5,6,7-tetrahydro-1H-indazol-1-yl)ethyl)benzo[c][1,2,5]thiadiazole-5-carboxamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies N-(2-(3-(Pyridin-4-yl)-4,5,6,7-tetrahydro-1H-indazol-1-yl)ethyl)benzo[c][1,2,5]thiadiazole-5-carboxamide (CAS 1797225-29-6), a certified reference material (molecular formula C21H20N6OS, MW 404.49 g/mol) for analytical method development and quality control.
The molecular framework of N-(2-(3-(Pyridin-4-yl)-4,5,6,7-tetrahydro-1H-indazol-1-yl)ethyl)benzo[c][1,2,5]thiadiazole-5-carboxamide (C21H20N6OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
