Description
3-Amino-1,2,4-triazole-5-carboxylic acid 3-Amino-1,2,4-triazole-5-carboxylic acid hemihydrate 3-Amino-5-carboxy-1H-1,2,4-triazole hydrate 304655-78-5 5-Amino-1(H)-1,2,4-triazole-3-carboxylic acid RC-76032 (CAS 304655-78-5) is a high-purity analytical reference standard with the molecular formula C3H8N4O2H2O and a molecular weight of 150.14 g/mol.
3-Amino-1,2,4-triazole-5-carboxylic acid 3-Amino-1,2,4-triazole-5-carboxylic acid hemihydrate 3-Amino-5-carboxy-1H-1,2,4-triazole hydrate 304655-78-5 5-Amino-1(H)-1,2,4-triazole-3-carboxylic acid RC-76032 (C3H8N4O2H2O) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 3-Amino-1,2,4-triazole-5-carboxylic acid 3-Amino-1,2,4-triazole-5-carboxylic acid hemihydrate 3-Amino-5-carboxy-1H-1,2,4-triazole hydrate 304655-78-5 5-Amino-1(H)-1,2,4-triazole-3-carboxylic acid RC-76032 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.
