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.
1-Chloro-3-methyl-6,7,8,9-tetrahydro-5H-pyrido[4,3-b]indole (CAS 61191-14-8), molecular formula C12H13ClN2 and molecular weight 220.70 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Chloro-3-methyl-6,7,8,9-tetrahydro-5H-pyrido[4,3-b]indole (C12H13ClN2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. 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 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).
CATO manufactures 1-Chloro-3-methyl-6,7,8,9-tetrahydro-5H-pyrido[4,3-b]indole 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.
