Chemical Structure
Description
The occurrence of 2-((4-Fluorobenzyl)amino)-4-(4-isopropylphenyl)-4-oxobutanoic acid is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-((4-Fluorobenzyl)amino)-4-(4-isopropylphenyl)-4-oxobutanoic acid (CAS 1024697-65-1), molecular formula C20H22FNO3 and molecular weight 343.39 g/mol, is a CATO reference standard with documented purity and traceability.
2-((4-Fluorobenzyl)amino)-4-(4-isopropylphenyl)-4-oxobutanoic acid (C20H22FNO3) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 2-((4-Fluorobenzyl)amino)-4-(4-isopropylphenyl)-4-oxobutanoic acid 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.
