Chemical Structure
Description
2-((4-Acetylphenyl)amino)-3-chloronaphthalene-1,4-dione (CAS 130089-98-4) is a high-purity analytical reference standard with the molecular formula C18H12ClNO3 and a molecular weight of 325.75 g/mol.
The molecular framework of 2-((4-Acetylphenyl)amino)-3-chloronaphthalene-1,4-dione (C18H12ClNO3) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 2-((4-Acetylphenyl)amino)-3-chloronaphthalene-1,4-dione 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.
