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 4,7-Dihydro-4-oxo-2-[(triphenylmethyl)amino]-3H-pyrrolo[2,3-d]pyrimidine-5-carboxaldehyde (CAS 1019853-65-6), a certified reference material (molecular formula C26H20N4O2, MW 420.46 g/mol) for analytical method development and quality control.
4,7-Dihydro-4-oxo-2-[(triphenylmethyl)amino]-3H-pyrrolo[2,3-d]pyrimidine-5-carboxaldehyde (C26H20N4O2) contains a steroid core, 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. 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.
