Chemical Structure

2-(1H-Indol-3-yl)-3-methylnaphthalene-1,4-dione CAS 647862-40-6 chemical structure

Description

2-(1H-Indol-3-yl)-3-methylnaphthalene-1,4-dione (CAS 647862-40-6), molecular formula C19H13NO2 and molecular weight 287.31 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(1H-Indol-3-yl)-3-methylnaphthalene-1,4-dione (C19H13NO2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. 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 2-(1H-Indol-3-yl)-3-methylnaphthalene-1,4-dione 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.
