Chemical Structure
Description
The molecular framework of 1-(2-Chlorophenyl)-3-(1-(3-(thiophen-3-yl)-1,2,4-oxadiazol-5-yl)cyclohexyl)urea (C19H19ClN4O2S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
1-(2-Chlorophenyl)-3-(1-(3-(thiophen-3-yl)-1,2,4-oxadiazol-5-yl)cyclohexyl)urea (CAS 1396865-24-9), molecular formula C19H19ClN4O2S and molecular weight 402.90 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
