Description
Compared with other compounds in its class, the molecular weight of 459.48 g/mol gives 2-({[6-amino-5-cyano-4-(2-nitrophenyl)-1H,4H-pyrano[2,3-c]pyrazol-3-yl]methyl}sulfanyl)-4,6-dimethylpyridine-3-carbonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-({[6-amino-5-cyano-4-(2-nitrophenyl)-1H,4H-pyrano[2,3-c]pyrazol-3-yl]methyl}sulfanyl)-4,6-dimethylpyridine-3-carbonitrile (CAS 328068-41-3), a certified reference material (molecular formula C22H17N7O3S, MW 459.48 g/mol) for analytical method development and quality control.
The molecular framework of 2-({[6-amino-5-cyano-4-(2-nitrophenyl)-1H,4H-pyrano[2,3-c]pyrazol-3-yl]methyl}sulfanyl)-4,6-dimethylpyridine-3-carbonitrile (C22H17N7O3S) is characterized by a steroid core, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
