5-(2-Chlorophenyl)-1,3-diphenyl-1H-pyrazole CAS 55042-82-5

Description

The occurrence of 5-(2-Chlorophenyl)-1,3-diphenyl-1H-pyrazole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 5-(2-Chlorophenyl)-1,3-diphenyl-1H-pyrazole (CAS 55042-82-5), a certified reference material (molecular formula C21H15ClN2, MW 330.81 g/mol) for analytical method development and quality control.

5-(2-Chlorophenyl)-1,3-diphenyl-1H-pyrazole (C21H15ClN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, 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.

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 5-(2-Chlorophenyl)-1,3-diphenyl-1H-pyrazole 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.
