Chemical Structure

methyl 9-ethyl-1-(hydroxymethyl)pyrido[3,4-b]indole-3-carboxylate CAS 2668259-67-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including methyl 9-ethyl-1-(hydroxymethyl)pyrido[3,4-b]indole-3-carboxylate.

methyl 9-ethyl-1-(hydroxymethyl)pyrido[3,4-b]indole-3-carboxylate (CAS 2668259-67-2), molecular formula C16H28N2O3 and molecular weight 296.41 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of methyl 9-ethyl-1-(hydroxymethyl)pyrido[3,4-b]indole-3-carboxylate (C16H28N2O3) 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).

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

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.
