Chemical Structure
Description
(E)-{1-[2-(4-fluorophenyl)cyclopropyl]ethylidene}amino 3-methoxybenzoate (C19H18FNO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
(E)-{1-[2-(4-fluorophenyl)cyclopropyl]ethylidene}amino 3-methoxybenzoate (CAS 338401-24-4) is a high-purity analytical reference standard with the molecular formula C19H18FNO3 and a molecular weight of 327.35 g/mol.
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.
