Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 260.68 g/mol gives Methyl 6-chloro-9H-pyrido[3,4-b]indole-3-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Methyl 6-chloro-9H-pyrido[3,4-b]indole-3-carboxylate (CAS 110522-03-7), a certified reference material (molecular formula C13H9ClN2O2, MW 260.68 g/mol) for analytical method development and quality control.
The molecular framework of Methyl 6-chloro-9H-pyrido[3,4-b]indole-3-carboxylate (C13H9ClN2O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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 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 Methyl 6-chloro-9H-pyrido[3,4-b]indole-3-carboxylate 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.
