Chemical Structure

1-Ethyl-1H-pyrazole-3,4-diamine dihydrochloride CAS 1431962-42-3 chemical structure

Description

1-Ethyl-1H-pyrazole-3,4-diamine dihydrochloride (CAS 1431962-42-3), molecular formula C5H10N4HCl and molecular weight 162.62 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrile group, chlorine substitution, 1-Ethyl-1H-pyrazole-3,4-diamine dihydrochloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 162.62 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.

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.
