3-(4-Cycloheptyl-5-mercapto-4H-[1,2,4]triazol-3-yl)-N,N-diethyl-benzenesulfonamide CAS 522624-30-2

Description

3-(4-Cycloheptyl-5-mercapto-4H-[1,2,4]triazol-3-yl)-N,N-diethyl-benzenesulfonamide (CAS 522624-30-2) is a high-purity analytical reference standard with the molecular formula C19H28N4O2S2 and a molecular weight of 408.58 g/mol.

3-(4-Cycloheptyl-5-mercapto-4H-[1,2,4]triazol-3-yl)-N,N-diethyl-benzenesulfonamide (C19H28N4O2S2) contains a steroid 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.
