The occurrence of 6-Methyl-1-(4-methylphenyl)-1H,2H,3H,4H,9H-pyrido[3,4-b]indole 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.
6-Methyl-1-(4-methylphenyl)-1H,2H,3H,4H,9H-pyrido[3,4-b]indole (CAS 529476-77-5), molecular formula C19H20N2 and molecular weight 276.38 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-Methyl-1-(4-methylphenyl)-1H,2H,3H,4H,9H-pyrido[3,4-b]indole (C19H20N2) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
As a certified reference material (CRM), 6-Methyl-1-(4-methylphenyl)-1H,2H,3H,4H,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.
