Chemical Structure

3-Aminopyrazole Hydrochloride CAS 34045-29-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 119.55 g/mol gives 3-Aminopyrazole Hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Aminopyrazole Hydrochloride (CAS 34045-29-9) is a high-purity analytical reference standard with the molecular formula C3H5N3HCl and a molecular weight of 119.55 g/mol.

Owing to a nitrile group, chlorine substitution, 3-Aminopyrazole Hydrochloride is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 119.55 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.
