Description
As a certified reference material (CRM), N-((1-Ethyl-4-methyl-1H-pyrazol-5-yl)methyl)-1,4-dimethyl-1H-pyrazol-3-amine hydrochloride 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.
N-((1-Ethyl-4-methyl-1H-pyrazol-5-yl)methyl)-1,4-dimethyl-1H-pyrazol-3-amine hydrochloride (CAS 1855950-22-9), molecular formula C12H19N5HCl and molecular weight 269.78 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, N-((1-Ethyl-4-methyl-1H-pyrazol-5-yl)methyl)-1,4-dimethyl-1H-pyrazol-3-amine hydrochloride is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 269.78 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
