Chemical Structure
Description
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.
4-(3-(Benzo[d][1,3]dioxol-5-yl)-1H-pyrazol-5-yl)-1-((2-nitrophenyl)sulfonyl)piperidine (CAS 1030386-38-9), molecular formula C21H20N4O6S and molecular weight 456.47 g/mol, is a CATO reference standard with documented purity and traceability.
4-(3-(Benzo[d][1,3]dioxol-5-yl)-1H-pyrazol-5-yl)-1-((2-nitrophenyl)sulfonyl)piperidine (C21H20N4O6S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
