Chemical Structure
Description
The occurrence of (5-Amino-1-(3-chlorophenyl)-1H-pyrazol-4-yl)(4-bromophenyl)methanone is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (5-Amino-1-(3-chlorophenyl)-1H-pyrazol-4-yl)(4-bromophenyl)methanone (CAS 618091-52-4), a certified reference material (molecular formula C16H11BrClN3O, MW 376.64 g/mol) for analytical method development and quality control.
(5-Amino-1-(3-chlorophenyl)-1H-pyrazol-4-yl)(4-bromophenyl)methanone (C16H11BrClN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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-Amino-1-(3-chlorophenyl)-1H-pyrazol-4-yl)(4-bromophenyl)methanone 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.
