5-Amino-1-(2,4-difluorophenyl)-3-methyl-1H-pyrazole-4-carbonitrile CAS 1020057-92-4 chemical structure

Description

The occurrence of 5-Amino-1-(2,4-difluorophenyl)-3-methyl-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.

CATO supplies 5-Amino-1-(2,4-difluorophenyl)-3-methyl-1H-pyrazole-4-carbonitrile (CAS 1020057-92-4), a certified reference material (molecular formula C11H8F2N4, MW 234.20 g/mol) for analytical method development and quality control.

5-Amino-1-(2,4-difluorophenyl)-3-methyl-1H-pyrazole-4-carbonitrile (C11H8F2N4) 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 5-Amino-1-(2,4-difluorophenyl)-3-methyl-1H-pyrazole-4-carbonitrile meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
