Chemical Structure
Description
The occurrence of 5-Amino-1-[3-(trifluoromethyl)phenyl]-1H-pyrazole-4-carbonitrile is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Amino-1-[3-(trifluoromethyl)phenyl]-1H-pyrazole-4-carbonitrile (CAS 956930-23-7), molecular formula C11H7F3N4 and molecular weight 252.20 g/mol, is a CATO reference standard with documented purity and traceability.
5-Amino-1-[3-(trifluoromethyl)phenyl]-1H-pyrazole-4-carbonitrile (C11H7F3N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine 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-(trifluoromethyl)phenyl]-1H-pyrazole-4-carbonitrile 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.
