Chemical Structure
Description
2-(1,2,3-Triazol-1-yl)acetohydrazide Hydrochloride (CAS 1877910-73-0), molecular formula C4H7N5OHCl and molecular weight 177.59 g/mol, is a CATO reference standard with documented purity and traceability.
2-(1,2,3-Triazol-1-yl)acetohydrazide Hydrochloride (C4H7N5OHCl) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-(1,2,3-Triazol-1-yl)acetohydrazide 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.
