Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
N-(4-Chlorophenyl)-N-(2-methyl-1-naphthyl)urea (CAS 860610-52-2) is a high-purity analytical reference standard with the molecular formula C18H15ClN2O and a molecular weight of 310.78 g/mol.
The molecular framework of N-(4-Chlorophenyl)-N-(2-methyl-1-naphthyl)urea (C18H15ClN2O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
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.
