Chemical Structure
Description
(3-(2,4-Dichloro-5-fluorophenyl)-1-(2-methoxyphenyl)-1H-pyrazol-4-yl)methanol (CAS 618441-97-7), molecular formula C17H13Cl2FN2O2 and molecular weight 367.20 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, (3-(2,4-Dichloro-5-fluorophenyl)-1-(2-methoxyphenyl)-1H-pyrazol-4-yl)methanol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 367.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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.
