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.
CATO supplies 1-(2-Fluorophenyl)-4-(mesitylsulfonyl)piperazine (CAS 496019-91-1), a certified reference material (molecular formula C19H23FN2O2S, MW 362.46 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, 1-(2-Fluorophenyl)-4-(mesitylsulfonyl)piperazine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 362.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
