Chemical Structure
Description
7-tert-Butyl 1-methyl 3-methyl-5H,6H,7H,8H-imidazo[1,5-a]pyrazine-1,7-dicarboxylate (CAS 1359655-89-2), molecular formula C14H21N3O4 and molecular weight 295.33 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H21N3O4, 7-tert-Butyl 1-methyl 3-methyl-5H,6H,7H,8H-imidazo[1,5-a]pyrazine-1,7-dicarboxylate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 295.33 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
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.
