Chemical Structure
Description
n-(2,5-Difluorobenzyl)-1-methyl-1h-pyrazol-4-amine (CAS 1006957-57-8), molecular formula C11H11F2N3 and molecular weight 223.22 g/mol, is a CATO reference standard with documented purity and traceability.
n-(2,5-Difluorobenzyl)-1-methyl-1h-pyrazol-4-amine (C11H11F2N3) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), n-(2,5-Difluorobenzyl)-1-methyl-1h-pyrazol-4-amine 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.
