Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

Methyl 2-amino-1-(2-hydroxyethyl)-1H-pyrrolo[2,3-b]quinoxaline-3-carboxylate (CAS 433706-93-5), molecular formula C14H14N4O3 and molecular weight 286.29 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Methyl 2-amino-1-(2-hydroxyethyl)-1H-pyrrolo[2,3-b]quinoxaline-3-carboxylate (C14H14N4O3) is characterized by a nitrogen-containing heterocyclic scaffold, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
