Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-N-ethylpyridine-2,3-diamine dihydrochloride (CAS 1197720-71-0), molecular formula C7H11N3HCl and molecular weight 173.64 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, chlorine substitution, 2-N-ethylpyridine-2,3-diamine dihydrochloride is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 173.64 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 2-N-ethylpyridine-2,3-diamine dihydrochloride 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.
