Chemical Structure
Description
tert-butyl 5H,6H,7H,8H-[1,2,4]triazolo[4,3-a]pyrazine-6-carboxylate (CAS 1989659-06-4), molecular formula C10H16N4O2 and molecular weight 224.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of tert-butyl 5H,6H,7H,8H-[1,2,4]triazolo[4,3-a]pyrazine-6-carboxylate (C10H16N4O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
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.
