Chemical Structure
Description
CATO supplies 1-(2-Chloro-6-fluorobenzyl)-5-methyl-1,2-dihydro-3h-pyrazol-3-imine (CAS 925200-31-3), a certified reference material (molecular formula C11H11ClFN3, MW 239.68 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution, 1-(2-Chloro-6-fluorobenzyl)-5-methyl-1,2-dihydro-3h-pyrazol-3-imine is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 239.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
As a certified reference material (CRM), 1-(2-Chloro-6-fluorobenzyl)-5-methyl-1,2-dihydro-3h-pyrazol-3-imine 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.
