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.
Cyclohexyl 3-(4-chlorophenyl)-3-(phenylsulfonyl)propanoate (CAS 2376300-22-8) is a high-purity analytical reference standard with the molecular formula C21H23ClO4S and a molecular weight of 406.92 g/mol.
Owing to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, Cyclohexyl 3-(4-chlorophenyl)-3-(phenylsulfonyl)propanoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 406.92 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
