Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 4-Methyl-1-(4-methylbenzyl)-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 201.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
4-Methyl-1-(4-methylbenzyl)-1,2-dihydro-3h-pyrazol-3-imine (CAS 1174833-98-7), molecular formula C12H15N3 and molecular weight 201.27 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
