3,4,5,6-Tetrahydro-1H-azepino[4,3,2-cd]indole CAS 5698-18-0 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 3,4,5,6-Tetrahydro-1H-azepino[4,3,2-cd]indole.

3,4,5,6-Tetrahydro-1H-azepino[4,3,2-cd]indole (CAS 5698-18-0), molecular formula C23H20N2O5S and molecular weight 436.48 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3,4,5,6-Tetrahydro-1H-azepino[4,3,2-cd]indole (C23H20N2O5S) is characterized by a flavonoid core, an amide group, a sulfone 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
