5-Amino-1-(4-chloro-2-fluorophenyl)-3-methyl-1H-pyrazole-4-carbonitrile CAS 2197063-20-8

Description

Compared with other compounds in its class, the molecular weight of 250.66 g/mol gives 5-Amino-1-(4-chloro-2-fluorophenyl)-3-methyl-1H-pyrazole-4-carbonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Amino-1-(4-chloro-2-fluorophenyl)-3-methyl-1H-pyrazole-4-carbonitrile (CAS 2197063-20-8), molecular formula C11H8ClFN4 and molecular weight 250.66 g/mol, is a CATO reference standard with documented purity and traceability.

5-Amino-1-(4-chloro-2-fluorophenyl)-3-methyl-1H-pyrazole-4-carbonitrile (C11H8ClFN4) 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.

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-(4-chloro-2-fluorophenyl)-3-methyl-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.
