Chemical Structure
Description
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.
Sodium ((4-chlorophenyl)sulfonyl)((4-cyano-3-methyl-1-phenyl-1H-pyrazol-5-yl)carbamoyl)amide (CAS 194542-56-8), molecular formula C18H14ClN5O3SNa and molecular weight 438.84 g/mol, is a CATO reference standard with documented purity and traceability.
Sodium ((4-chlorophenyl)sulfonyl)((4-cyano-3-methyl-1-phenyl-1H-pyrazol-5-yl)carbamoyl)amide (C18H14ClN5O3SNa) contains a salt form, a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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).
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.
