Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 5-Tosyl-5H-pyrrolo[2,3-b]pyrazine-2-carboxylic Acid (CAS 1201630-75-2), a certified reference material (molecular formula C14H11N3O4S, MW 317.32 g/mol) for analytical method development and quality control.
5-Tosyl-5H-pyrrolo[2,3-b]pyrazine-2-carboxylic Acid (C14H11N3O4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
