Chemical Structure
Description
(1-(2-Fluorophenyl)-3-(4-methoxyphenyl)-1H-pyrazol-4-yl)methanol (CAS 618383-20-3) is a high-purity analytical reference standard with the molecular formula C17H15FN2O2 and a molecular weight of 298.31 g/mol.
(1-(2-Fluorophenyl)-3-(4-methoxyphenyl)-1H-pyrazol-4-yl)methanol (C17H15FN2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 (1-(2-Fluorophenyl)-3-(4-methoxyphenyl)-1H-pyrazol-4-yl)methanol 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.
