1-(4-(Tert-butyl)phenyl)-5-(2,4-dichlorophenyl)-3-(4-fluorophenyl)-4,5-dihydro-1H-pyrazole CAS 301194-31-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(4-(Tert-butyl)phenyl)-5-(2,4-dichlorophenyl)-3-(4-fluorophenyl)-4,5-dihydro-1H-pyrazole.

1-(4-(Tert-butyl)phenyl)-5-(2,4-dichlorophenyl)-3-(4-fluorophenyl)-4,5-dihydro-1H-pyrazole (CAS 301194-31-0) is a high-purity analytical reference standard with the molecular formula C25H23Cl2FN2 and a molecular weight of 441.37 g/mol.

1-(4-(Tert-butyl)phenyl)-5-(2,4-dichlorophenyl)-3-(4-fluorophenyl)-4,5-dihydro-1H-pyrazole (C25H23Cl2FN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

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.
