Chemical Structure
Description
The occurrence of 5H-pyrido[4,3-b]indol-8-amine 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.
5H-pyrido[4,3-b]indol-8-amine (CAS 79642-24-3), molecular formula C11H9N3 and molecular weight 183.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5H-pyrido[4,3-b]indol-8-amine (C11H9N3) 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.
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 manufactures 5H-pyrido[4,3-b]indol-8-amine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
