Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Ethyl 7-methoxy-1H-pyrrolo[3,4-b]quinoline-2(3H)-carboxylate (CAS 34086-67-4), molecular formula C23H28IN9O4 and molecular weight 621.43 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 7-methoxy-1H-pyrrolo[3,4-b]quinoline-2(3H)-carboxylate (C23H28IN9O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
