Chemical Structure
Description
The occurrence of 1-(4-Fluorobenzyl)-5-methyl-1,2-dihydro-3h-pyrazol-3-imine 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.
1-(4-Fluorobenzyl)-5-methyl-1,2-dihydro-3h-pyrazol-3-imine (CAS 955969-72-9), molecular formula C11H12FN3 and molecular weight 205.23 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution, 1-(4-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 205.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
