Chemical Structure
Description
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.
Tris(3,5-dimethyl-1-pyrazolyl)methane (CAS 28791-97-1), molecular formula C16H22N6 and molecular weight 298.39 g/mol, is a CATO reference standard with documented purity and traceability.
Tris(3,5-dimethyl-1-pyrazolyl)methane (C16H22N6) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its physicochemical properties are representative of its class; 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
