Description
Compared with other compounds in its class, the molecular weight of 263.65 g/mol gives 1-[4-Chloro-3-(Trifluoromethyl)Phenyl]-4,5-Dihydropyrazol-3-Amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-[4-Chloro-3-(Trifluoromethyl)Phenyl]-4,5-Dihydropyrazol-3-Amine (CAS 77992-21-3), a certified reference material (molecular formula C10H9ClF3N3, MW 263.65 g/mol) for analytical method development and quality control.
1-[4-Chloro-3-(Trifluoromethyl)Phenyl]-4,5-Dihydropyrazol-3-Amine (C10H9ClF3N3) 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 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).
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 1-[4-Chloro-3-(Trifluoromethyl)Phenyl]-4,5-Dihydropyrazol-3-Amine 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.
