Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-[(2,4-Dichlorophenyl)methoxy](1-{2-[4-(propan-2-yl)phenyl]cyclopropyl}ethylidene)amine.
(E)-[(2,4-Dichlorophenyl)methoxy](1-{2-[4-(propan-2-yl)phenyl]cyclopropyl}ethylidene)amine (CAS 338392-35-1), molecular formula C21H23Cl2NO and molecular weight 376.32 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C21H23Cl2NO, (E)-[(2,4-Dichlorophenyl)methoxy](1-{2-[4-(propan-2-yl)phenyl]cyclopropyl}ethylidene)amine contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 376.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
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.
