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.
CATO supplies 7-[(tert-Butoxy)carbonyl]-5H,6H,7H,8H-imidazo[1,5-a]pyrazine-3-carboxylic acid (CAS 1432058-58-6), a certified reference material (molecular formula C12H17N3O4, MW 267.28 g/mol) for analytical method development and quality control.
The molecular framework of 7-[(tert-Butoxy)carbonyl]-5H,6H,7H,8H-imidazo[1,5-a]pyrazine-3-carboxylic acid (C12H17N3O4) 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. 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.
