Chemical Structure
Description
The occurrence of (1-(3-Chlorophenyl)-3-(4-fluorophenyl)-1H-pyrazol-4-yl)methanol is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(1-(3-Chlorophenyl)-3-(4-fluorophenyl)-1H-pyrazol-4-yl)methanol (CAS 618444-40-9), molecular formula C16H12ClFN2O and molecular weight 302.73 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, (1-(3-Chlorophenyl)-3-(4-fluorophenyl)-1H-pyrazol-4-yl)methanol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 302.73 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
