Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(2-Ethylphenyl)-3-(2-(4-fluorophenoxy)ethyl)urea.
1-(2-Ethylphenyl)-3-(2-(4-fluorophenoxy)ethyl)urea (CAS 1171989-36-8), molecular formula C17H19FN2O2 and molecular weight 302.34 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(2-Ethylphenyl)-3-(2-(4-fluorophenoxy)ethyl)urea (C17H19FN2O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 1-(2-Ethylphenyl)-3-(2-(4-fluorophenoxy)ethyl)urea under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
