Chemical Structure
Description
The occurrence of Indolo[3,2,1-ij]quinolino[4,5-bc][1,5]naphthyridine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Indolo[3,2,1-ij]quinolino[4,5-bc][1,5]naphthyridine (CAS 85412-78-8), a certified reference material (molecular formula C20H11N3, MW 293.32 g/mol) for analytical method development and quality control.
The molecular framework of Indolo[3,2,1-ij]quinolino[4,5-bc][1,5]naphthyridine (C20H11N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Indolo[3,2,1-ij]quinolino[4,5-bc][1,5]naphthyridine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
