Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1H-pyrazole-3-carboximidamide hydrochloride (CAS 166197-22-4) is a high-purity analytical reference standard with the molecular formula C4H6N4HCl and a molecular weight of 146.58 g/mol.
Owing to a nitrile group, chlorine substitution, 1H-pyrazole-3-carboximidamide hydrochloride is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 146.58 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).
CATO manufactures 1H-pyrazole-3-carboximidamide hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
