Description

Compared with other compounds in its class, the molecular weight of 339.82 g/mol gives 2-[(4-tert-Butylphenyl)amino]-3-chloro-1,4-dihydronaphthalene-1,4-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-[(4-tert-Butylphenyl)amino]-3-chloro-1,4-dihydronaphthalene-1,4-dione (CAS 179115-43-6), a certified reference material (molecular formula C20H18ClNO2, MW 339.82 g/mol) for analytical method development and quality control.

The molecular framework of 2-[(4-tert-Butylphenyl)amino]-3-chloro-1,4-dihydronaphthalene-1,4-dione (C20H18ClNO2) is characterized by a steroid core, 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 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).

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-[(4-tert-Butylphenyl)amino]-3-chloro-1,4-dihydronaphthalene-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.
