Chemical Structure
Description
1-Methyl-N-((3-methyl-1h-pyrazol-4-yl)methyl)-1h-pyrazol-4-amine (CAS 1156890-84-4) is a high-purity analytical reference standard with the molecular formula C9H13N5 and a molecular weight of 191.23 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 1-Methyl-N-((3-methyl-1h-pyrazol-4-yl)methyl)-1h-pyrazol-4-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 191.23 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).
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), 1-Methyl-N-((3-methyl-1h-pyrazol-4-yl)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.
