6-(Ethylsulfonyl)pyridazin-3(2H)-one CAS 62645-16-3

Description

Compared with other compounds in its class, the molecular weight of 188.20 g/mol gives 6-(Ethylsulfonyl)pyridazin-3(2H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6-(Ethylsulfonyl)pyridazin-3(2H)-one (CAS 62645-16-3), molecular formula C6H8N2O3S and molecular weight 188.20 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 6-(Ethylsulfonyl)pyridazin-3(2H)-one (C6H8N2O3S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.
