Chemical Structure
Description
The occurrence of 1-(Furan-2-carbonyl)-4-(naphthalene-2-sulfonyl)piperazine is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1-(Furan-2-carbonyl)-4-(naphthalene-2-sulfonyl)piperazine (CAS 428827-12-7), a certified reference material (molecular formula C19H18N2O4S, MW 370.42 g/mol) for analytical method development and quality control.
1-(Furan-2-carbonyl)-4-(naphthalene-2-sulfonyl)piperazine (C19H18N2O4S) 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.
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.
