3-((5-Chloro-2-methoxyphenyl)amino)-1-(naphthalen-2-yl)propan-1-one CAS 477328-96-4

Description

3-((5-Chloro-2-methoxyphenyl)amino)-1-(naphthalen-2-yl)propan-1-one (CAS 477328-96-4), molecular formula C20H18ClNO2 and molecular weight 339.82 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C20H18ClNO2, 3-((5-Chloro-2-methoxyphenyl)amino)-1-(naphthalen-2-yl)propan-1-one contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 339.82 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), 3-((5-Chloro-2-methoxyphenyl)amino)-1-(naphthalen-2-yl)propan-1-one 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.
