Chemical Structure

4-(3-Nitro-1H-1,2,4-triazol-1-yl)butan-2-one CAS 60728-92-9 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

4-(3-Nitro-1H-1,2,4-triazol-1-yl)butan-2-one (CAS 60728-92-9), molecular formula C6H8N4O3 and molecular weight 184.15 g/mol, is a CATO reference standard with documented purity and traceability.

4-(3-Nitro-1H-1,2,4-triazol-1-yl)butan-2-one (C6H8N4O3) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
