Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
N-[3-(Dimethylamino)propyl]-4-(2-ethylbutanoyl)-1H-pyrrole-2-carboxamide (CAS 478259-82-4), molecular formula C16H27N3O2 and molecular weight 293.40 g/mol, is a CATO reference standard with documented purity and traceability.
N-[3-(Dimethylamino)propyl]-4-(2-ethylbutanoyl)-1H-pyrrole-2-carboxamide (C16H27N3O2) contains a nitrogen-containing heterocyclic scaffold, an amide 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.
