Chemical Structure

9H-Pyrido[3,4-b]indole CAS 244-63-3 chemical structure

Description

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.

CATO supplies 9H-Pyrido[3,4-b]indole (CAS 244-63-3), a certified reference material (molecular formula C11H8N2, MW 168.19 g/mol) for analytical method development and quality control.

The molecular framework of 9H-Pyrido[3,4-b]indole (C11H8N2) 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

As a certified reference material (CRM), 9H-Pyrido[3,4-b]indole 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.
