Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 362.85 g/mol gives 1-(5-Chloro-2-methoxyphenyl)-3-(5-hydroxy-3-phenylpentyl)urea distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-(5-Chloro-2-methoxyphenyl)-3-(5-hydroxy-3-phenylpentyl)urea (CAS 1795485-11-8), a certified reference material (molecular formula C19H23ClN2O3, MW 362.85 g/mol) for analytical method development and quality control.
The molecular framework of 1-(5-Chloro-2-methoxyphenyl)-3-(5-hydroxy-3-phenylpentyl)urea (C19H23ClN2O3) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
