Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
(1-(3-Chlorophenyl)-3-(2,4-dichloro-5-fluorophenyl)-1H-pyrazol-4-yl)methanol (CAS 618441-75-1) is a high-purity analytical reference standard with the molecular formula C16H10Cl3FN2O and a molecular weight of 371.62 g/mol.
The molecular framework of (1-(3-Chlorophenyl)-3-(2,4-dichloro-5-fluorophenyl)-1H-pyrazol-4-yl)methanol (C16H10Cl3FN2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine 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.
